As somebody else pointed before, the XBox 360 and the PS3 aren't much different from PC gaming. Except for the fact the PC is far more powerful and Sony internal studios produce better HD products than most studios. However, the Wii is a completely different beast. You can do really different things from it and there are several titles for offline multiplayer action. Besides, Nintendo is unmatched as a game developer, so you have plenty of great titles available.
