I'm trying to like Google Wave, but at the end of the day, I can't. I don't really give a damn about it. Recreating movie scenes is cute, but hardly the life-changing paradigm they predicted. RPGs, on the other side...
According to experts, Google Wave is perfect to organize role playing games. Its persistent nature allows to keep a precise record of all that is happening. Players can keep three waves:
The few games I'm following typically have at least three waves: one for recruiting and general discussion, another for out-of-character interactions ("table talk"), and the main wave where the actual in-character gaming takes place. Individual players are also encouraged to start waves between themselves for any conversations that the GM shouldn't be privy to. Character sheets can be posted in a private wave between a player and the GM, and character biographies can go anywhere where the other players can get access to them.
Yeah, I don't give a damn about Google Wave. Next! [Ars Technica]
