I've downloaded Art of Balance so far, and I think it is really great. Based on other people's suggestions I've decided against Furry Legends. So for my next game I'm deciding between Pearl Harbor Trilogy, Rage of the Gladiator, Max and the Magic Marker, and Jett Rocket. Max and the Magic Marker was a game I was really excited about, but impressions seemed kind of mixed, and I heard there were some annoying bugs. Everything I've seen about Rage of the Gladiator looks great and I do like Punch-Out (although not as much as platformers). Pear Harbor Trilogy looks fun, but I've never really played an air combat game,the closest thing for me is the plane game in Wii Sports Resort which I liked. Jett Rocket looks really nice, but I'm concerned about the short length (I'm not really a completionist either so I don't want to collect everything.) and I've read that there are some annoying bugs on that one as well.
I'm going to wait to get my last game until Monday and Dive comes out, then I'll decide between that, Cave Story, and the other games on my list I didn't download.
