MP Etiquette

[bleach168]

I've just started playing MP in Dominions. In general, it seems people just play however they feel like. Everybody I've interacted with has been pretty honorable but in different ways. I'd like to know if there are some unwritten rules for how to conduct yourself when playing MP Dominions 2.

Some situations I am unclear about,

1. Emails. As far as I know, it's okay to contact and discuss things through emails even though there is no ingame mechanic to allow it. Is this true for all games?

2. Non-Aggression Pacts. When someone says "NAP" I know it means a non-aggression pact but does it also imply a 3-turn warning to break? Or does that have to be explicitly stated? Also, what happens if someone breaks the treaty without the 3-turn warning. Does this ever happen?

3. Alliances. If you ally someone, is it your responsibility to announce it? If you want to prevent yourself or your ally from getting attacked, I would think you would want to announce it as a deterrent.

4. War. Is it okay to attack someone without warning if there had been no previous agreements? Or should you give them at least a 1 turn warning?

5. How common is it to gang up on the "supposed" leader?

6. Do people carry grudges over from one game to the next?

7. Trading. Is there a universal guide as to how much items and gems are worth in trades? Like how much a gem would cost in gold? Or does this differ in every game?

8. If two of your neighbors start exchanging blows do you:
a) Help the person losing
b) Help the person winning
c) Don't do anything and let it resolve

9. At what point, in your opinion, is it okay to go AI.

10. Mutual victories. How common is it for an alliance to just be declared the winner and the game ends like that?

Thanks for any answers.
