Civilization 5 Gods and Kings vs Civilization 4

Civ V > Civ IV

civ V is easier to get into, has some pretty graphics, steam integration, and nice overall.

But if i had to choose one of the two to play for eternity, i'd choose Civ IV over Civ V, in top of that, civ 4 have more mods that add hughe replayability

even the lead designer has posted in his kickstarter about civ V 'things' that could have been done better http://www.kickstarter.com/projects/jonshafer/jon-shafers-at-the-gates

in civ 4 you can stack units on one tile which has changed in civ 5 -> great improvement!

From the experiences ive had I much prefer Civ IV, however I haven't played Civ V with any of the expansions yet.

Civ 5 is much easier and beginner-friendly, but Civ 4 has much better AI, better multiplayer, better diplomacy, deeper strategy and way better mods.

The AI in CIV sucks and GOD e KINGS isn't that good.
