Issuing a moratorium on how a thing "would be great on Vita," so, uh, I don't know what else to say. Sly Cooper is fun. And now the HD bundling of the first three games is playable on the Vita.
Of course, it's also 30 bones and you can probably track down the PS3 version for less than half that price on Amazon. But, hey, it's a great fit for the Vita. Oops!
