It's kind of like Zelda but with more focus on combat than exploration and no puzzles. I've also heard comparisons to Dark Souls but I think that has more to do with the difficulty (although it's not nearly as hard as those games imo). While it's not a particularly long game, it's challenging enough that it doesn't feel too short. Plus the art and music are both amazing.
And it's supposed to be coming to PS Vita eventually (if it's cross buy I'll probably play it again on there since it seems like it would be a great portable game).
