not sure if these are in the game sence I only played the demo but having prequels sequels remakes and spinoffs would be very helpful when contuning a game or what ever. you select an older game and tell it if you are making a remake or a sequel.
some of the options would have the game coppied with II or 0 or what ever attached to the name it would remember the settings you had for the game and let you change them. the Remake option will have most of the settings grayed out because it has to be the same type and style of game.
