The idea of a split screen minecraft game or meeting up to play together just baffles me.
My friends and I have a server together that we all play on... but like Zachnorn said, its up for weeks at a time as we expand whatever it is we are building. Honestly, the interactiveness of Minecraft multiplayer isn't so much "playing together" as it is being like "hey come look at this awesome thing I just made over here."
It's a sand box game that I spend hours and hours creating in. It's good if you guys are enjoying the 360 version but I honestly do not know how Minecraft the way I play it could translate to that medium.
