Yeah but why? Are units more balanced? One thing I've noticed about Civ 3 is the battles are all random. It was weird switching from the RTS genre to TBS. I expected units to be more statistical instead of dice rolls. The only other experience I have with this type of game is Romance of 3 Kingdoms which I played like 10 years ago and it confused me a ton.
Battles in Civ4 are less random and even carry light RPG elements. I've never played Civ5 but from what I've heard, the combat in general is improved but the AI is too dumb to adjust to it.
Play Civ4 later, darn it! Also this thread has inspired me to perhaps think about giving Civ4 another playthrough. Maybe after my blind Portal playthrough?
EDIT: I've never played Civ3, but from what I've heard, you merely need to link each resource with a road to gain access to that resource. In Civ4, a resource must actually be linked with a tile improvement as well as a road (for example, a mine is needed to gain access to copper and a pasture is needed to gain access to cows).
