As a fan of Final Fantasy, I think that Dissidia was more of a nostalgic collective item then a game to be played. I mean, for those of you who have been with the Final Fantasy series since its beginning, I am sure you didn't mind experiencing 3D action with your favorite NES and SNES characters. Putting a voice on them also gave you that incredible satisfaction of knowing that these old characters were not left to rot in a drawer.
Dissidia was definetly made for those hardcore gamers that have followed the series since its beginning and I am glad Square made it.
