Actually, I like Civ III a whole lot more than Civ II, even with Test of Time.
Civ II bores the crap out of me. Part of it is that only two terrain types--grasslands with shields and hills--are good for any reason. The awful diplomacy also stands out.
And, get this, I actually won a game of Civ III without controlling 3/4 of the planet. That never happens in Conquest II, uh, I mean Civ II.
Are there things I want in Civ III that aren't there? Yeah, a few. I'm expecting, though, that long before I'm desperate for them, an expansion pack will come along with some enhancements. In the meantime, when MOO3 comes out, I'll likely pick that up, and I'll dream about when MoM2 comes out (not that crap they tried to feed me with the one expansion to Civ II).
