Just because it would make money doesn't mean it was as good as nostalgia seems to make it to some. To be honest, it's not even the best FF game since it came out and if we're using younger gamers as the bar here it's a REALLY low bar. Everything now is all FPS crap and graphics are more important than game play or story to most kids.
Don't get me wrong, I played the hell out of FF7 when it first came out. However it REALLY doesn't hold up. Best left to nostalgia IMHO. Focus on making the new ones good.
