I have to say Final Fantasy, its the reason that i simply love Jrpgs unfortunatly the latest games werent that good.... ( Final fantasy XIII and XIII-2) and now it was announced Lighting Returns: Final Fantasy XIII... lets see if it get better...
i have MANY favorites but those favorites have been lacking lately with me not buying the last couple games (like resident evil i only bought revelations on 3ds but not operation raccoon city and not getting re6 right away) i would say SILENT HILL its the only game series where i own EVERY game and completed them all
I would say Zelda, because all of their games have a had great graphics, good stories, and lots of cool things to do in the game besides fighting enemies. I don't like the younger Link games as much as the older Link games, because when he's older he either has a horse or a Loftwing. Zelda is awesome.
