Fighting game or not, it has the protagonist and antagonist of:
FFVII (The money cow strikes back)
FFVIII (best selling FF title in Japan and top 3 worldwide)
FFVI, IX and X (every one of them got close to the top 2 in Japan, and X is 2nd worldwide)
I, II, III and IV (Old FF fans like me say hello)
If the game is good, if that is not enough to draw at least 1 million LTD i don't know what is enough...
