yeah, I think dissidia is a good game and a good idea. I like the VS mode of it and that you are free to choose the individual you will play with. if you have local friends you can even fight with them( if they have a PSP and the game offcourse)

The story was ok, but not the best. I prefer the original stories much much more
the battle system was great, challenging and fun.
overall, a good game to spend your time with
