The only games I have on the wii right now is Brawl, Xenoblade Chronicles, Sonic Colors and NSMB. I don't know if even that was worth it. I'll wait and see if some more games I like come out for the Wii U for this new gen.
I got mine preordered, along with some games. I'm getting ZombiU, New Super Mario Bros. U, maybe Batman, And of course Nintendo Land that's bundled in. As much as I love my PS3, Nintendo was my babysitter as a kid, I've been a lifelong Nintendo Nerd as my brother used to say.
