At first glance, this might seem like the favorite game category rehashed, but I don't think so. This question eliminates considerations like Tetris, Gran Tourismo and even Pacman (I don't know if Pacman speaks in the new game, but on the old 2d, he's just a yellow pie eating dots). I think that in order to qualify for favorite character, the character in question must have a personality. For example, Jimmy Patterson in Medal of Honor: Frontline, has basically no personality. We see his entire world from over the top of a gun barrel. We don't know if he's happy, sad, frightened, macho or wimpy. He has no personality. Does this mean you can't select an FPS character? No, I'd argue that the Master Chief in Halo has a personality. Not well defined, but we know he's macho and fearless. The same lack of personality can be said of the character you play in Grand Theft Auto or Morrowind. We never hear these characters speak, or see them react to things. Does the guy in GTA care that he's been ordered to go kill a lot of people he doesn't know? Does the character in Morrowind feel guilty for stealing things? These are questions we don't know the answer to. We never even see so much as a facial reaction. So I'd like to elimate all the non-characters out there. No Ice Climbers, or Grand Theft auto thugs, or Jimmy Patterson. So long as the character has a personality, either gained through dialogue or reaction, it's a valid choice. Last, the question is about playable characters. So Cid from Final Fantasy VII is valid, but Sephiroth would not be (yes, Sephiroth is in a flashback battle, but really, not a playable character).
