Because it has the games I want. No rubbish, I like the "childish" games. SMG, SSBB, TP, they're just the games I like the best.
It has motion controller, which IMO is awesome, I don't think it will be easy to go back to normal contollers (SSBB will be OK, due to Wiimote+nunchuck)
It has the most focus on offline multiplayer, which I like better than online.
It doesn't have great graphics, and therefore has more of the "happy look" so I'm happy while playing, which is the most important for me.
The Virtual Console is a great addition for me - I've only been around since N64 era.
Because it does NOT have voice-chat. I dislike voice chat.
