Civ 5 does not seem to have any kind of war weariness, like Civ 3 or 4 had. War doesn't really seem to be any drawbacks, as long as you don't annex or puppet cities. War gives generals (which can give GA), and pillage seems to pay more than the repairs cost. The Aztecs even get culture for fighting. Is war all good in Civ 5? Or have I missed something?
