The only thing I don't like about the 3d is the fact that (at least from the pictures I've seen) they look pretty bad, the buildings look choppy and the units look square. The cool thing about civ3 was that you could play the game on practically any machine no matter how old and still get amazing gameplay. 3d is going to put a strain on civ fans who don't have high end graphics cards or simply don't like 3d. Honestly, I don't see how 3d is going to make the game more "immersing". I get just as into civ3 games as the "civanon" people get; hell I've been playing almost non-stop for a week since I got the cold war scenario. The fact that civ4 is turn based is the only thing that's saving the game from being a RAM leech. I guess I'll have to see how civ4 runs once it comes out and see whether I'll make the reluctant change from 3 to 4 at all, but I hope with everything in me that I'll be wrong and the graphics will be breath taking and the game even better than it ever was and draws in huge ammounts of fans so that firaxis can get the recognition it deserves for making great games from the mainstream crowd.
