I got a Wii when they came out (Christmas '06 I believe) and I haven't played it since last spring. I Played Zelda Twilight Princess religiously until I got stationed in Louisiana and now I spend all my free time playing WoW with my gf or watching movies. I don't have a whole lot of free time either. Shift work is killer when you're not on days, lol. As for good games for those systems, I really couldn't say, lol. I pretty much got my Wii solely to play ToS. *grin* And play I did... until I got busy. I know that I will HAVE to make time for the new LEGO Indiana Jones game, so my Wii will get plenty of use this summer, teehee! If you haven't tried the LEGO Star Wars and you're even half a fan of the movies, definitely rent it and you'll go buy it the next day. AND it's one you can beat in a week or two of casual playing or you can beat it "perfect" and take a couple months. It's not a traditional RPG but it definitely should not be missed.

Over all, I'd say wait it out and see if you notice some other RPGs that you would be interested in coming out on the Wii. Do some research into GameCube games too. There's some good stuff there, too. I just don't know of any off the top of my head except maybe FF Crystal Chronicals. I haven't played it but I've hear good things.
