there is alot of those issues in a colonize-only-own-type games. especially in larger games, 3 way alliances tend to develop between ice-rock-gas dwellers. then the alliances tend to face off against each other.

with only own type and only own atmosphere, you would probably get more of a free-for-all. you could run a 5 player game with the same effect if you just use the colonize own atmosphere option..

some people would have planets that very few and far between, im just guessing, but im thinking maybe one good planet per 3 systems. i guess a good way to find out would be to start a game with ancient race on, and see how many green *s you get.
