I think the multi-format game I've played the most is Sonic Racing Transformed and now I guess Zombi U is multi-format so that can be included too.
Generally been disappointed with multi-format wii u games. I have a ps3 and 360 and they generally play better on those consoles. The cpu bottleneck in wii u really causes the frame rate to collapse in some games under high load and even in the fast areas is weaker than the older consoles.
