To be honest, I don't see games like Wii Sports and Wii Play games as adult games. They're just very accessable. They're games for adults that want to be like kids again. A game like BioShock (to choose a more recent example) seems (I obviously haven't played it, I'm basing this on what I've read) a lot more "mature". And a game like ICO is infinitly more mature than Wii Sports or Wii Play. It's like saying Harry Potter is an adults book. There's nothing deep about it, it's enjoyable because it makes you fell like a kid again. Real mature books are things like Ninteen Eighty-Four or Foundation. They make you think. I'm not saying a game like ICO is as mature as Ninteen Eighty-Four but it's certainly a lot close than Wii Sports.

Anyway, I really hope that these adults that are being raked in by Wii Sports and Wii Play decide to give gamer games a go. Maybe they'll see how truely mature a game can be. If they don't, I see this big "non-gamer" push being completely useless to me. All we're going to see resources (not all resources, though) being switched to making overly simplistic games and "boundary breaking" games being left in the wayside again.
