This one is made redudant because Dissidia 012 exists and includes almost all of the content this includes and more but It would still be nice to have it. It's still a little piece of history that helped shaped the Playstation Portable into what it was. It's a tecnical marvel, pushing the PSP as far as it could go with flashy, engaging combat while also having a great roster to choose from.
Multiplayer side of things back in the day was Hilariously unbalanced but I still had a blast with friends.
