 They felt that in the first game, Aldo's story and the "film story" were divorced too much from one another, and they wanted to ensure this didn't happen in the sequel.As a result, the game is not a direct retelling of the film, but instead non-canonically places Dominic directly into scenes in which he was not present in the film.They also consciously gave Fredo a much more central role than he has in the film, having him leave Cuba with Michael rather than staying behind.
