I think the bugs are a bit exaggerated, least based on my experience. I don't know how many people remember just how bad MoM was when it was first released -- and the frequent crashes never actually got repaired for that game. I know that some people have had really bad experiences as far as crashing is concerned, with the day 0 patch. But already, the game seems to be far more stable than MoM EVER was.
I do agree with you, though, that we should expect more from game releases, and that this game is kind of conservative, and I can't wait to see what this game will look like in a few months with all the coming additions and mods. Also, problems and all, it currently IS the most addictive 4X game I've played since Alpha Centauri.
