Super Paper Mario = Definite get, I believe Mario is best in his original platforming form.
Pokémon Battle Revolution = I'll probably get it, but I'm not super excited for it. Looks a little lacking in content much like the Stadium games.
Mario Strikers = Looks like a lot of awesome tastefully violent fun, online will probably be enough to get me to buy it.
Big Brain = Hell no, the only people I know who likes these games are old people and my nerdy friend. It's just not for me.
