Yes, Homeworld was fun :) But I never was very good at RTS genre, so I prefer turn-based games (well, KSP is exception :D), like Master of Orion, Alpha Centauri or Endless Space.

Oh, X3... X universe is very tempting - I was into it in times of X: Beyond the Frontier, but I didn't fell in love with X3 Terran Conflict, I don't know why. Maybe I was already too spoiled with way simpler and easier games.

And third person mentioning FTL in first place ;) Maybe I'll try to get it too and play it :)

Nice list ^^ I'll tell you - KSP is different than most of them ;) There is free demo on their site (but it's quite outdated, I don't know if they'll release new version of demo anytime soon), so you can take a look how you like this kind of game. Plus there is lots of streams and YouTube videos to check out how game looks in "vanilla" mode and modded. Because there is huge and very nice community, lots of mods and developers are very good people too :)

I don't like subscriptions too, that's why I didn't even try EVE Online. But Mass Effect is great - I just loved the story :)

I'm a bit ashamed to not play such classic like KotOR yet, but it's waiting on DVD for it's turn, I promise :D

My computer will be too weak for this game, but maybe in few years... ;) I'm looking at it and graphics and gameplay looks very promising :)

I had no idea, there is BSG board game... Thanks for info :) But I don't think I'll be able to gather enough players, so with board games I'll stick to chess and go probably ;)
And a BIG plus for liking Alpha Centauri. I checked Civ Beyond Earth in Steam Free Weekend, but it's not even close to fun of AC.
