This is hard. >_<
They all win for being angsty anti-heroes who're caught up in it all and lead the story... but really. I'd have to go for Zidane [Cloud's getting over-rated these days. With Tidus and Squall being under-rated, and in my opinion which ain't so great, Tidus was the worst of them all.] Zidane, for being in a real fantasy game with hard technology just starting to advance, it's the age of romance, where the whole world is developing. He is my favourite for being a tad different from the other heroes who're all the same. Being a sly shifty untrustworthy hero. FTW.
