1st of all im gonna agree with Omecle and LionX

Having Played FFXI for 2 years it deffinitly HAS a complex and interesting story. Morso than Most if not All other MMO's.

Although Id say that the "Generation" of Games goes by the "Generation" of the Console its Played on.

1-3 = Nintendo = 1st Generation
4-6 = Super Nintendo = 2nd Generation
7-9(+Tactics) = Playstation = 3rd Generation
10-12 = PS2 = 4th Generation
13 = PS3 hopfully = would be 5th Generation
