'A few hours' is a very loose description of blitz games. They almost always last at least 2-3 hours, and I've played them as long as 8. That said, you will probably have difficulty finding players that want to blitz on very large maps, since 25+ provinces per player past turn 40 can already be nearing an hour per turn.

OUCH! Having never played this MP, I am having a hard time seeing how it takes that long. In the late game, I may take 15 minutes to complete a turn (except for LA Ermor, LOL), but definitely no longer. How does MP work? Does each player take thier turn and then the next player gets to try? I was under the impression that turn decisions were simultanious?
