There don't seem to be many games out for how old the system is... I'm playing Twilight Princess right now. Personally, I'd rather have a PS3, but wife enjoys the Wii and I don't think she'd really use a PS3.

Nintendos marketing strategy with the Wii store is brilliant. They're getting people to pay $5-10 for games they haven't made money on for YEARS. Or never have made money on, in the case of Sega Genesis games!
