Dont forget that Endless is still in alpha phase, there's a massive potential for it to suck terribly, since the internet that pays gets to have a say in the game...and how did that work out with that one movie, Snakes on a Plane was it? It looks nice enough, but still, its going for the "Civilization in space/wasnt MoO cool back in the day?" approach from what I've been able to gather, though I'm fairly ignorant towards it, not a fan of turn based.
Rebellion is nice enough though, granted it kinda invalidates new people getting Trinity since Rebellion has all that content, but I still happily recommend getting all of it to friends...so I can brutalize them slowly, start with Sins, then work up through the expansions.
Thanks for the game though Ironclad, I've happily played since the original release. Though I do admit that to begin with, I pirated the game...for about twenty minutes then decided "the hell with this, its time to pay" and have bought every single release.
The only pause there was for Rebellion as soon as I saw it released, was due to my credit card being a lil iffy, but now, now I am a happy and proud owner of your games Ironclad and Stardock.
And if you can 64bit the next game...£$@# yes baby!
