Oh boy. First things first, I go to gamestop and take all of their overpriced secondhand games and consoles. After that, I'd go break into some houses just for fun.
I would kidnap master shefs of all my favorite restaurants and bakeries, confine them in my house, then make them teach how they cook/bake my favorite cuisine/breads.
The other thing I would absolutely do, is to kidnap all those who are crazy enough to kill/abuse innocent weaker lives (children/animals), confine them, take them out one by one, and smash their heads with a huge hammer, break them into fragments.
