atmosphere / type of world handicap

[trooper]

I think that some races have a natural bonus due to their homeworld conditions. The couple no atmosphere/rock world gives the best chances to find suitable planetes (even if no atmosphere life form should be rare...) because of the moons. the worse couple is perhaps gas world or liquid world and no atmosphere...

The race I'm creating would come from a liquid world, with methane or hydrogen atmosphere. don't you think it's a hard start world for a game ?
