umm... outpost 1? its old... and... i think the community managed to fix most of the bugs... but its still not totally complete... i dont think...

really good story... basicly... the earth is about to fracking go boom... but humans know this... so they build a freaking space ship (and you have to manage how much stuff you want to bring... and you cant take everything)... and they run away... and you have to be lucky enough to find a marginaly habital planet... (you can lose the game before you even start building your first building)... and then you have to be very carefull in the beginning of the game cause if you dont get your population down to the surface fast enough... they all tend to die... cause they are no longer in stasis.... it took me a few tries to just get past the initial shizznits... and then it becomes a turn based colony sim. still rather hard though... on the easy difficulity... 
outpost one was a colony builder... outpost 2 was a rts... but you had to manage your population as well. really... really... good story line with outpost 2 though... the little novela that you read after every mission is really good. I think outpost 2 was alot more fun... while still had some of the elements of outpost one... it was set later... and has war... and had something that will prolly end up giving you nightmares... ( i mean seriously... the intro vid+the eden beginning campain vid+ the first chapter of the eden book is friggen scarry! read it before you do the first mission... )
edit: Oh ya, they are both free from that website... you may need some old video codecs... for the movies (the game loses alot without them) but all those people in their forums are really nice and will help with anything. (as long as you do a search or 2 first... since almost everything has already been answered.)
