Mmm, some might say the original was the best. They are all good in their own way. I just get annoyed by the fundamental changes in the building benefits between the versions.
Yeah. There's fairly major changes in pretty much everything between versions: tech, wonder, leader benefits, tile improvement benefits, etc. Oh well.
A game "feature" for the real dedicated players. Gives you a chance for a 10 minute power nap at 4am while concentrating on strengthening your defences.
Yes, you're right, it crawls in late game, even on an 8-core Mac Pro.
Hah, well I never thought about it that way. I remember one time I reloaded an old saved game and didn't have the "Show Enemy Movements" or whatever unticked. You have no idea (or maybe you do?) how infuriating it is to watch your city or large stack of units get attacked one by one and watching the animations go back and forth for two hours. Gah!
