I think they'll keep up their good work. Their low point for me was Sunshine. That was such a bad game. Galaxy was amazing. It made me smile while I played it, just like Mario 64 did. I think that's the key for me. If I can play a game, and smile, really have fun just doing it, It's a good game. Some games just make me feel that I "have to" beat it, as in I've already put in a few hours, so I should get it done. I think if Nintendo keeps up the level of work from Galaxy, They'll be fine.
