As we all know, Square Enix has a bit of an obsession with Lightning. She has been on the cover of every game despite the fact that she shared the stage pretty evenly with all the other party in XIII and wasn't even in the party of XIII-2. This has all culminated into a final game where she takes the center stage as your only playable character.
I can't comment on the newest game since it is not out yet in the US, but I personally find Lightning to be a pretty bland character out of the original party. If you were in charge of this final game, who would you have preferred to be the main character and why?
