Well all RPGS have guided storylines in some way, some may give u a bit more room to roam, but no matter what a programmer has to program that in there so its there, you r limited. The first few ffs allowed a bit more choice over character, and ff11 is the mmorpg so theres no arguing those.

As far as the rest, I would say they are roleplaying games... I get so deep into the story and character ans start thinking I am that character, that... well, its just the same ^_^
