Just noticed Civilisation V in the app store. Anyone here playing it like to give me a heads up as to likely performance and other observations since playing it? I'm on the fence as to whether to get it. I've heard it's quite buggy for mac and has no ability to edit modes/scenarios etc... I pretty much always create my own world as close to the current maps and civilisations as possible. I've heard that's not currently possible on the mac. Is that true?
