Thanks again for Civ! And agreed -- I can feel a marathon multiplayer session sometime in our future, haha.

Also, give the CK2 demo a shot, if you have time: http://store.steampowered.com/app/203770/
There's one for EU3, as well (albeit not the full, completed version of the game, which is "Chronicles"): http://store.steampowered.com/app/25800/
They're similar games, except in EU3, you play as a country, while in CK2, you play as a person and his/her descendents.
