Hmm... well, I hope that it works with GC-controller-compatible Wii games! Otherwise they're releasing this thing for Smash and just about nothing else, since who knows how many other Wii U games would really support this when the Wii U Pro controller's got more buttons and is more standard for the system. But there are a bunch of Wii games that can play on the Wii U and work with Gamecube controllers, so I hope this will work with those as well as with Smash.

Also, of course, it's very interesting that Nintendo is both releasing a GC controller adapter for the Wii U mostly just for SSB, and that they're holding a SSB Wii U tournament during E3. They're obviously interested in getting the hardcore SSBM competitive community interested in this game. Well, I hope the game's great!

I think it's pretty interesting that Nintendo used GC controllers with these things for Wii U Smash at E3. Really shows how hard they are catering to the hardcore fans... we'll see how the gameplay holds up though.
