Any Civ2 stalwarts tried Civ4 yet?
Yes.
As implied by the above emoticon, I am not wowed. It's too soon to say whether I'd recommend it generally. It's got a lot of good ideas, and a few lame ones. It's hard, too, to know which of the lame ideas were intended and which can/will be fixed in expansions. This much is certain: it IS somewhat buggy and the Civilopedia needs LOOOTS of work.
If you are CERTAIN your machine can run it smoothly, and if dropping $50 is not much of a hardship for you, it's worth picking up.
But otherwise, I'd at least wait until there are enough patches and expansions to make it better. (And more moddable, as they insist it will be -- surpassing Civ3 in that respect at the very least. I hope.)
And BTW, all that talk from Sid about how graphics aren't the most important thing for a game like this? Yeah, that was all a lot of B.S. -- Civ4 is graphically excessive. The 3D looks nice but really is not necessary.
I may have more to say about Civ4 later, after I've given myself some more time to ruminate. But that assumes I'll be willing to put up with its slowness and its other, more intrinsic problems.
In fact, just last night I started a new Civ2 game and found myself marveling at its simplicity, its elegance. How many games can you marvel at all over again once every five years or so?
