Hmm, where to start...
- I love the fact that there is no one 'correct' tech path to take.
- I like the fact that the 'feel' of the game is slower and yet sped up in that the first few millenia seem to take forever to do/build something but there are always multiple other things to plan, think about or do, to keep you busy in the mean time.
- I like the changed diplomacy. No more abusing the AI, or at least no more abusing it as much.
- I love the new religions! If for nothing else than trying to get all the different missionaries out and sneak them into a place with Theocracy, or closed borders is a fun game to play in the middle of playing the game too.
- I like the unit variety, not just in promotions but the whole difference between gunpowder, armor and siege categories and how they all balance out.
- I like how the AI's seem to have their own distinct personalities and they aren't all the same with a different GUI.
- I LOVE the music. The intro reminds me of the intro to the Lion King, and I am ever so glad I managed to find a pre-order copy of the game a few days after it launched so that I have the music CD now.
- I like the new terrain variations. A hill isn't necessarily a hill, or a hill, they can all vary. That, plus the improved and enhanced terrain improvements even makes what was 'routine' and dull fun again with trying to figure out what best goes where.
- I like the graphics. Game play always should trump graphics if one had to be concentrated on, but the world looks so rich and alive it's hard to imagine going back and playing even a half dozen turns on Civ3, much less SMAC or one of the earlier versions of the game.

, like something I would do 
... 4)The promotions add a type of realistic depth that was lacking in Civ3- archers are a prime example, they can be offensive in some cases and excellent defenders in other -unit type, unit function, and terrain are accounted for in Civ4.
, and that is how it should be
