I take weird ideas, and then take them one step further. I've been a writer all my life, and a worldbuilder almost as long, and I like to make people laugh. I can go to dark places, but I don't find them altogether that interesting, and much prefer something lighthearted with fanged rainbows or denture trade routes (that also involve prunes).
Worldbuilding (obviously), Tabletop roleplaying, Lego MOC building (though less so now: sort of in my Dark Ages, as they say).
Everything Star Wars, Most things Star Trek, The Princess Bride, Guardians of the Galaxy (1 & 2), The Lego Movie, The Lego Batman Movie, etc.
As in TV Shows? Star Trek: The Next Generation, Avatar: The Last Airbender, Warehouse 13, The Orville.
... All of them? Uh... Lord of the Rings, Howl's Moving Castle, Little Women, Discworld (notably Thud!, Guards! Guards!, and Snuff), Once On A Time (by A. A. Milne), The Hitchhiker's Guide to the Galaxy (but the radio shows are best).
J. R. R. Toklien, Louisa May Alcott, Terry Pratchett, C. S. Lewis, A. A. Milne, Ray Bradbury, Douglas Adams.
No Man's Sky, Tooth and Tail, Elite: Dangerous, Stardew Valley, Horizon: Zero Dawn, Super Smash Bros. Brawl, Scrap Mechanic.
