I'd embark on an epic quest, gathering brave warriors including, but not limited to Dwarves, Elves, Gnomes, Goblins, and Homestar Runner, and my party and me will ride a giant bird/reptile/snake/gerbil/flying boat. And I will get a girlfriend that casts heal spells but stinks at fighting, and also hates me but falls for me at some point. I might hate her too. Depends on if she's snobbish.
And we will fight enemies that include, but are not limited to Evil goblins, Birds, Alligators, Crocadiles, Stick figures, Evil kittens, Dinosaurs, Vegetation, and Martians.
Along the way, I will perform menial tasks for villagers including, but not limited to retrieving lost wallets/watches/handkerchiefs/keys/kittens/books/rocks/wood scraps, reuniting a modern Romeo and Juliet, and killing some difficult-to-find pest-beasts for seemingly useless but collective trickets/rare stones/garbage that can be traded with a crazy person for nice things.
And I will do minigames including, but not limited to washing dishes, racing giant birds/reptiles/snakes/gerbils, washing cars, holding off an army in an RTS style, hacking, slot machines, and card games for either gold pieces or trinkets/rare stones/garbage.
Eventually, I will fight some demon/dark angel/andriod/warlock/master swordsman/evil kitten to the death. In space. Or another dimension. And he will be mind-controlling my girlfriend/Homestar Runner at some point, and I must kill her/him for the greater good, even though I'd much rather not. Then I kill the demon/dark angel/andriod/warlock/master swordsman/evil kitten, final cinematic plays, we go to credits, extra cinematic showing me and my girlfriend (Who, against natural logic, survived) getting married, The End.
Or, I will get tired from finding all the secrets, save and go do something else.
