Harvest Moon (pick almost any): start out with no money and a cow, sell everything you own, almost never sleep, eat weeds, be forced into marriage a year in no-matter your relationship status, save something in the process, hate trying to get better plants, go to parties sometimes, be annoyed by sprites, be too tired to do anything, begin contemplating trying to kill your cow to sell it's meat but cant, start wishing there was a harvest moon game where you weren't against eating mammals or slaughtered birds.
Gallop Racer2006: get a stable, buy a horse, race it, get more horses, race them, make money, breed horses, race them, repeat.
Kingdom Hearts: Beat up on your favorite Disney villains to save Mickey, who annoys the hell outta you
Okami: you're a goddes reborn in a male wolf-body and have to save Nippon from several baddies, the main villain of which being (in my opinion) and angry seal in a snowglobe - but the gameplay is gorgeous so take forever to end the game.
