ill start by saying what youre missing out on by playing rebirth instead of the demon blade
-they translated a lot of sword names and all the difficulty names, which is pretty dumb and detracts from the japanese style the game is going for
-having a big screen to truly appreciate the game on

other than that, this game is the definitive version of muramasa. all the new characters are fun and have unique and varied movesets. you get the updated textures as well, which is amazing considering how absolutely gorgeous the original game is.

if you dont have a vita, id recommend playing the demon blade for wii for now. the new content doesnt ineract with the older content at all, in fact by the game they're considered sort of as if theyre separate games.

overall, one of my favorite games and an absolute must play for literally any human being with a pulse.
