ive played the older 1 be4 at my old xbox-> it got speedboat racing, some kinda jumping pool race, collect stuff like bikini/present/etc, & i think something else [watch poll dance? sun bathing? talking&dating?], ive forgotten its been so long ago 
im pretty sure they will upgrade alot in this 1, maybe sum moar sports type, buy real estate, photo+pose mode, dating, open world+free roam, etc...
if they dont add more stuff then this game is just another dirty cheap cash grab with tons of costume dlc    which will be wayyy too much as we seen in doa series...
