Played 10 minutes of the first Toybox area, on Wii U.
The area you wind up in after the tutorial(or during the tutorial?).
Anyway, did it splitscreen with a sibling, and it's amazingly fun. Each character has witty banter against the other, my Randall was chattin' it up with Jack Sparrow!
When I tried going to the museum/hall of heroes(?) area, the game froze, and locked up the Wii U. Eh...
Restarted, and jumped straight into Lone Ranger co-op, and the world is pretty big(some areas are locked off at the start, so the beginning area is pretty big).
The combat is fun, riding horses and donkeys is fun, but unfortunately the framerate dips down quite a bit every now and then. It's not horrific drops, but its definitely noticeable. Still playable, though.
I'm gonna go back in a while to do the Incredibles playset.
