I was going to try multiplayer but that was clearly an afterthought. Not even a chat room before joining a game or pings or anything resembling a good multiplayer interface.
Well multiplayer in CIV is somewhat difficult anyway. With any normal multiplayer game the game is normally over in at most an hour. So there isn't much risk getting a game going with someone. With Civ5 the game is just getting started an hour in. You'd probably be lucky to get a game completed in a week (assuming you all have a life). It would royally suck to get 3 hours in and have your opponent go AFK for the next month. So with Civ scouting out who your playing with is a much bigger issue and doesn't seem like something solved by the game itself. I'll probably stick to playing people I already know.
