Writing is the main one.
Oof. Hard question. See favorite writers for suggestions, since I have a hard time choosing.
Brandon Sanderson, Brandon Mull, J. R. R. Tolkein, Katie Cross, Sara Prineas, Gerald n. Lund, Shannon Hale, Charles Dickens, and more I can't think of at the moment.
Minecraft, Galactic Civilizations Three, and a fair number of Wii and Xbox 360 games.
