So I picked up Civ 4 complete, Civ 5 GOTY and Stronghold in a an amazon deal a little whiles back for 20 bucks.

Got around to playing Civ 5 two days ago.

Played the tutorial campaign to completion straight through and played an entire game, 3500BC-1960AD, last night. (Germans ftw)

Is 4 really worth playing after running through 5 at this point?
