Did anyone ask for this port?
Epic Mickey 2 came and went, and was pretty much a step back from the original in every way. What started out as a promising homage to Walt Disney's first major creation -- Oswald the Lucky Rabbit -- ended up in disaster both critically and commercially.
I'm not sure who exactly asked for a Vita port of the game, but nonetheless, the Vita port comes with touch screen capabilities, as well as ad hoc network functionality. Point blank, I would not recommend picking up this game until it's deeply, deeply discounted.
