In a vain attempt to drag this thread back on its actual topic(s):
Who prefers a genre other than fantasy for TTRPGs? What games do you prefer? What would it take for that preferred genre, do you think, to better compete with fantasy in the TTRPG mindspace?
I don’t prefer (medieval-ish) fantasy over sci-fi in RPG: I like them both equally. In a RPG, I tend to look for elements that makes us experience something different from “reality”. This can take many forms but I prefer RPGs that bring up the supernatural (1920s Cthulhu, Weird West, Vampires, etc), the romanticized elements of high fantasy (elves and swords and magic), or advanced technology opening possibilities beyond our world (sci-fi).
I’m not a big fan of the very weird and gunzo, or science-fantasy à la He-Man etc.
And then there’s Star Wars, which I love. SW is fantasy at heart but closer to sci-fi when it comes to codify the setting as game engine. It’s “rules” are closer to those of sci-fi, and RPGs tend to bring out the technical stuff in Star Wars (for the better of for the worse). Then again, I build my last Star Wars RPG hacking the game engine of a Lord of the Ring RPG, so even that works…
[edit] rereading my post, I notice it doesn’t answer the question.
I think the RPG offer is actually quite wide; I don’t think there much to be done to improve the place of other genres in the RPG mindscape other than somehow convincing more people to play these games. More visibility could help, as well a production value that can rival with D&D. But the products are there. If we ignore the demographics of who is playing what and the number of copies sold by game, I’m not certain fantasy RPGs are that much superior in number of games.
