I apologized if this has already been answered, but I can't find anything like it through Google.
Alright, so me and a couple of friends want to play some Civ 5 together. Is it possible to play Civ 5 on 2 computers with 3 people online? Two friends are in another state, so they would have to be in a makeshift hotseat while I'm just with my own computer.

I imagine this contorted way of doing it wouldn't be possible with just the base game, so can I do with with GMR?

Also, as an somewhat unrelated question, does GMR support in-game turn cycling? As in, will I have to restart the game every time the turn switches over?

Thanks
