Ditto. It's a superb game. I don't really care that the expansion will add a third player, I just want more buildings and the new resources! If it includes a third player (board), then it's going to necessarily be a pretty hefty box for an expansion, though. Probably not ideal for the Brasileiros. :/
I will probably play this game only with my girlfriend so the 3rd player won't be important. But more stuff to do in the game is always better.
It's never ideal for us. But most of my games I bought when someone went abroad and it will stay that way forever.
