Re: Senior question
 

My cutoff depends. If I have control over many systems, I usually make the cutoff at 100%, because I have lots of planets to colonize. Otherwise, it can be as low as 80%. Also, I always build a RD, and usually a SY. The SY is optional for smaller size planets though.

Re: Senior question
 

If Min 90+ or Org 130+ or Rad 110+= dedicated min/org/rad planet
If Min 90+ AND Rad 110+ = monolith colony
If resources low = A Shipyard and the remaining slots with research or intel facilities.
All breathable planets above small size (medium, large and huge) have a shipyard (and sometimes a BSY or two), regardless of the use of the planet (resource, research, intel)
All my systems must have a minimum of 1 shipyard and 1 resuply depot (i end with around 3 or 4 shipyards using the above rules)
If i have a min/org/rad/monolith planet with less than 10 facility slots i build 2/3 resource extraction and 1/3 resource storage facilities in the planet...
When i have training centers i build them in the unbreathable/low resources planets that previously had one shipyard (that i maintain) and some researh facilities (that i scrap for the new facilities)

The resource concentrations can increase or decrese according to the needs of my empire and the availability of a particular resource...

As a end result i normally have 3 or 4 shipyards for every system (being 2 or 3 in tiny moons)and 1 ressuply depot per system.... if i need additional ship-producing capabilities in a system i build additional BSYs...

Re: Senior question
 

In general, I rarely build Resupply bases. Maybe one for every 6 or 7 systems. But, I try to locate them strategically. As to mining extraction? I must be conceited (LOL)...I have to be in trouble before I start building mineral extraction on things less than 3 digits.

Pertaining to your other questions...things that get built (and how many different kinds on one planet) depend on the locations, how well I'm doing, what I need most, etc. So, it's difficult to answer. One rule of thumb I usually follow: If I find a huge worthless rock, I'll put 29 research on it and a SY (for, hopefully, adding bonus multipliers later and platforms for protection till then).

Re: Senior question
 

You should only build such facilities on planets with at least 101% of the appropriate value. That would be very fun when playing with the Balanced Systems mod. *Whistles* http://forum.shrapnelgames.com/images/smilies/wink.gif

A bit more seriously, you might actually expect a couple of turns from me today. I am doing some catch up, and will play my own turns at Last.

Many thanks for the answers
 

They have given me 'food for thought' (as if I wasn't overweight already) http://forum.shrapnelgames.com/images/smilies/happy.gif

I tend to build an SY in every planet of my Home system(s). Naturally - this system is heavily defended.

I'm converting over to the all-or-none philosophy. It makes sense to me.

Just getting back to playing after a hiatus.
