nailer: That's quite a jump there, and considering how fun this game was (clearly not a 6.6)
Well, review scores were not as inflated back then, so 6.6 really did indicate a "fair" game. Not good, but not bad either. And if you were looking for an X-COM type game, Incubation really is significantly simplified from that, both in the tactical, and especially the strategic aspect. The single player campaign has its flaws, being more of a puzzle game at times. And while it might be aesthetically powerful (great visuals and sounds, especially for the time), if you place more emphasis on gameplay, that's not going to help much overall.
So even though I don't agree with that review entirely, I can see where he's coming from. And supposedly, the expansion fixes a lot of the abovementioned flaws.
Anyway, I definitely agree with the "VOTE VOTE VOTE" sentiment. X-COM stands at 139 votes, Incubation at 52 - how about giving the former some competition?
