Cross Link Scenarios: Adjustable difficulty

[Pyros]

Cross Link Scenarios: Adjustable difficulty

Adjustable difficulty related with the player’s WIN ratio

Concept: The more the player wins marginal victories the harder the game will be.

Mechanism of Balance based on Standard map/scenario:

1. Increase or decrease of hostile units performing active patrol duties
2. Increase or decrease of replacement points
3. Increase or decrease of auxiliary support units (air, artillery)
4. Increase or decrease of fortification points
5. Combination of 2 or more of the above

1. By increasing the presence of the active hostile units (not stationary) we add more opposition to the tactical plan of the player. Patrol routines will be discussed under the appropriate AI “patrol” section.
2. By decreasing the replacement points we counter the possibility that an experienced player will play the battles without loses, leading this way to unbalanced due to not anticipated evolution of his core army (bigger effect on small battles, smaller effect on bigger battles – depends on the ratio between core army & auxiliary army)
3. By increasing the auxiliary support unit we help player to achieve his objectives on assaulting units
4. By increasing the fortification points we help the player to avoid further friendly casualties
5. By making combinations of the above parameters we may adjust difficulty in a desirable effect.

We have to work with case studies of categories of players

The best system to achieve equilibrium for players that load/save (a lot) during the game will be to create "traps".
A "trap" is the cross-link path that is the result of 3 consecutive decisive victories (or even marginals).
If a player scores something different the he leaves the "trap" and procceeds to the normal campaign route.
The check will will go for a 2 or 3 consecutive decisive victories.

The maximum difficulty will have a limit, in general the Adjustable Difficulty will lead to a combination (permutation) of 3^2=9 possibilities (3 levels of hostile presence and 3 levels of replacement points).
The point is that a player may still be able to play the game at the max difficulty level (max enemies & min replacements points) and that this increased difficulty will force the (reload type of) player to lose more often and win harder.


Summary:

The player at the beggining of each Chapter he will gain some replacement points according to the level of adjustable difficulty (d, m, v). Then he will procceed to the Secondary mission (Sd, Sm, Sv) and by the outcome of his victory(?) he will procceed to the corresponding type of primary mission (Pd, Pm, Pv). The result of the primary mission will determine the new difficulty level (of the player) for the next Chapter.
The mechanism of calibration of each primary/secondary mission according to the appropriate difficulty will work by adding a percentage of active enemy patrol forces to the the standard mission. The main task for each Chapter will be to design one primary prototype mission and one secondary prototype mission and then calibrate or modify according these prototypes according to the difficulty level or mission type.

Wow, quite a lot to digest here. Looks good though. I particulary like the additional bonus&ambush scenario's for players who are doing either very well or pretty bad.

A couple of questions though to help me get a few things clear (and avoid later mix ups):

1) you mention losses, draws, marginal victories, medium victories and decisive victories. Is there already a mechanism (specific points ratio's after the battle for example) to determine in what category a result is placed or is that one of the things we'll have to work out later? How many categories of results are there for the battles?

2) When a player loses a secondary mission (search & destroy mission according to the 'Cross Link Scenarios: Mission type' thread) the campaign ends for him/her but not when losing a primairy (assault and defend missions mostly according to the 'Cross Link Scenarios: Mission type') or bonus mission (ambush & counterattacks according to the 'Cross Link Scenarios: Mission type' thread)?

Edit: besides the levels of victory mentioned above you also mention 'minor victories' in the 'Cross Link Scenarios: Mission type' thread.

Hi Remco,

I am leaving for work so I will post more details in a few hours

cheers,

The bonus mission are security valves to prevent abusing or early ending of the game. We are going to test this new system of campaign but I am confident that it will make the camapaign challenging for every skill and will add to the replayability of the campaign.
there are few other tools in the random effect of scenario designing that will add a lot to the campaign replayability.
BUT for sure the mechanism of adjustable difficulty is a NEW CONCEPT and need a lot of testing (but not extra designing work since the difficulty adjustments will be minor )

In order to keep workload to a logical size, I propose we keep 3 levels of adjustable difficulty and we split them among the different margins of battle outcome. If you are aware of the cross link availability of the campaign edit you will notice that depending of the battle outcome we may redirect a max of 5 directions of adjustable difficulty (decisive victory, marginal victory, draw, marginal loss, decisive loss)

The player never loses the campaign, simply if the player loses the secondary mission he ends the chapter.
Two comments on this:
1. The secondary mission will be easy, since the player will have to preserve the good status of his troops in order to play the primary mission (the scope of the secondary mission is to give the choice to the player to adjust the condition of battle for the next /primary mission, example normal hostile artillery or less?)
2. After the secondary mission the player will go directly to the cross-linked primary mission without getting replacements, so in the RARE event that a player loses the secondary mission he won't be able (logical) to win the primary mission, thus it is better that he exits the current Chapter and he may go to the next chapter in order to replenish/fix his casualties. But all these have to been tested.
3. The outcome of the secondary mission (in most cases) will vary between draw ot marginal victory and decisive victory. The mechanism of making the difference between the linkek primary mission will be whether the player will score a decisive victory or not. Believe me this is a bit complicated, but it can be done by special allocation of VP flags and modified extra value of certain hostile units.
Don't worry we are going to discuss many special techniquews in this project... LOL

That's what I thought indeed. So since the tree allows for just three different results (loss to draw, draw to medium and medium to decisive victory) I suggest we stick to some fixed terminology to represent these three to avoid mix ups and misunderstandings. I also suggest to change the 'ranged' results in the tree (loss to draw, draw to medium, medium to decisive) to fixed results (something like no-win result, partial victory, total victory). That way it is immediately clear what happens IF a certain result is obtained, WHEN a certain result is obtained (the range) isn't really necessairy to depict in the tree itself. A simple table next to it defining the 'no-win, partial and total results' will probably make things easier to read and understand, and is more functional. Right now it's somewhat confusing since it's not obvious to what path a draw or medium victory leads (both are in two ranges)?

The no-win, partial and total victory terms have the advantage that they aren't used elsewhere (marginal and decisive are as you mentioned above) nor commonly used in normal discourse so if and when we'll use these terms to refer to the tree it'll be clear someone is referring to the tree's outcomes and not something else.

Just trying to simplify some things here under the assumption that if they confuse me, they may confuse others too!

You are right Remco,

But this is only a schematic under discussion and to give you understand the new concept.
During the next weeks we will have to get in the heads of the players and after a lot of analysis we could see how these 3 difficulty margins will evolve…
For example, when I play a campaign, I don’t use at all, AUX units (provided by the designer) because I don’t want that my core army lose experience by potential killings.
I also always try to kill enemy units than to complete mission objectives for the same reason… by killing I (my core army) earn experience. In the end I win every battle with a decisive victory… and the campaign becomes not challenging (at all) after a certain point (elite units).
With the new concept… arrogant players like myself will lose half of their army in the BONUS mission and from that point and for a couple of mission (until the adjustable difficulty gets to the lower level) they will have a really hard time. The point is that we have to achieve a dynamic equilibrium and we have to take as a point of reference that the player in a 1:1 battle will try hard to achieve a draw (score/result).
Remco, think… the player will know that the AI will kick his *** (!) and won’t be so aggressive to achieve decisive victories! If you add to this the fact of uncertainty (due to low % hostile reinforcement along the edges of the map – simulation of hostile patrols) the game will become very interesting!

For sure, this is something totally new in the industry and we are going to be the pioneers!

As for the 3 level of difficulty I like the idea to use special terms but we should investigate more for these special margins… For example I assume that no player (no matter how rookie he is) will ever lose a battle in a campaign, so the first group could be from Decisive Loss to Marginal Loss.
Now, instead of going to the second margin, I will go to the third one…
If some one wins all the time and each battle with a decisive victory… then this guy should deserve a level by his own (I mean that a marginal victory is something close to the minor victory or even draw, BUT on the other hand a decisive victory is something that we can’t determine how far it is from the marginal victory… I am afraid that from this point someone may not understand my thoughts…LOL For example, If some drops an atomic bomb he will gain a decisive victory but what is the distance from the player with the atomic bomb and the player who won a marginal. In other words… the decisive is an upper limit, meaning that you can’t define this limit. On the other hand, the marginal victory is defined in relation with the Draw result…So for the third difficulty level I think we could use, just the Decisive victory result and for the second level of difficulty the Draw to Marginal victory result.
So, the paths to the 3 levels of difficulty could be defined as:

1. Decisive & Marginal Loss Path Green
2. Draw & Marginal Victory Path Blue
3. Decisive Victory Path Red

Hi Pyros,

that was mostly the editor in me. When I spot something which might be improved upon or simplified, even just a little bit, I can't resist pointing it out....

One thing is important though; we've probably all learned to avoid repetition and use different words which mean more or less the same when writing to make it more pleasing to read. It's likely second nature for most of us. However, that 'more or less' can lead to miscommunications and confusion when precise info needs to be passed on, especially in group efforts like ours where there are people from different countries (with slightly different interpretations in our english) and only text based communication. In those cases, strict use of terms (and it's repetitive nature) becomes an advantage. So it might be a good thing if we start developing our own 'vocabulary' for this project (for the really important bits like the victory levels in the tree or like what you have for the different types of scenarios: primairy, secondary and bonus) to help us make things clear to each other. It can save a lot of explaining back and forth later on.
I don't mean we need to make a dictionary or anything like that, but to be consistent in how we call certain aspects of the project.
