Is Yoshi's Wolly World pretty fun?
It really is. Ended up being one of the best games for Wii U - yeah, it has some familiar gameplay that's been present in everybody Yoshi title, but it does so much that's new and fresh too. And if you're trying to 100% it, it's got just that right amount of difficulty to make you keep coming back for more. I'd easily pay full price for the game, at $20, it's a no-brainer.
