Why don't you read Sulla's excellant synopsis of Civ V, and then judge for yourself.
Troll alert !!!Just don't listen to the Sulla Dinosaurs
Yes the AI is still pretty bad but in comparison to other games its actually not that bad.

If you want to play multiplayer go for it. Civ 5 Multiplayer >>> Civ 4 Multiplayer by a longshot even though it is more buggy. Humans can handle the interface and the Civ 4 multi lobby really has had a significant die off. Compare that to the various civ 5 multi groups and the general decline of league - civ 5 is a must for multi and a better experience than Civ 4.
I'm sure its been asked before, but if I were a Civ 4 player and played many hours with both expansions. Would I enjoy purchasing Civ 5 and the expansion?
Civ 4 AI is better suited for the system - but from a programming and actual standpoint it isn't "smarter" in fact is much more simplistic than Civ 5 AI
@ Tatran - So are you denying Sulla's synopsis is ancient and entirely out of date considering all of the changes to Civ 5 nowadays (Expansion, patches, AI enhancers, etc? Right so who honestly is trolling here lol...
