Bombadil is more of a personality litmus-test, which is why I mentally place you in the "staid" category. That's no crime. I've actually been thinking about this in the context of Prince's Zock Block podcast interview. There's (IMO) something very "direct" (treading lightly here!) about the vibe of Heavy Metal music---Prince's favorite/only genre of choice. Things like Bombadil, and the diversionary nature of that side-jaunt, may bother him for that reason. A "staid" fellow (like yourself?) might also find that kind of whimsy tiresome. In contrast, I enjoy whimsy (Winnie the Pooh, Wind in the Willows, The Hobbit, etc.) and feel that things like the quasi-mono-emotional, steady push-towards-a-goal (akin to Heavy Metal's adrenaline-rush), lacks nuance---the full dynamic range of tension and release. It's difficult to be surprised in a one-note/one-volume world. I've actually mentioned this to Prince a few times in the context of adventure design. In play, I believe there needs to be some paths that lead to the Bombadils of the world, because those hidden non-sequitars feel less contrived than a linear plot born from the human mind, and more natural.
