Wikia's are usually made by people who actually know what they're doing. And, as a person who bothered getting through FFX-2, I can say its accurate.
Lightning, at least 'right now', is the current face of Square Enix. 3 game in a 2-3 year period. That much is fact. They've recorded their largest loss of funds when FFXIII was released, and it was the worst selling game of the franchise with the standards of each game. Which may sound hard to believe; I barely did at first, read it in a Game Informer.
That being said...honestly...who the hell wouldn't want a female gunblade user who summons a horse over a spiky-haired tool with a large sword? Like holy crap, that'd be awesome.
