Can we get a list going of games that feature multiple generations of playable characters?
For example, in Record of Agarest War there are definite breaks where your main character picks a wife and then later on you play as their son. This reminded me of Dragon Quest V, which reminded me of Phantasy Star III.
More examples! Bass and Tina Armstrong in Dead or Alive, which is a fighting game. John and Jack in Red Dead Redemption, which is a third-person moseying game.
I'm sure it would be easy to pick out the RPG and SRPG games. What about FPS, fighting, racing, wrestling, third-person shooting games (etc.) that feature two or more blood-related characters you can play as in the same game? Even if it's for one mission or level.
