I think I have something for that!

At least you know your place ;)

I wouldn't count live cam as reality, unless they're roleplaying a character. Same with gonzo. There has to be a bit of suspension of disbelief that these are just real, normal people, not performers.

Non joke answer: anything with a "real life" scenario. So no cosplay, no fantasy creatures, no satire/parodies, etc. If the actors are playing like neighbours, doctor/patient, the pizza guy, a Tinder hookup, that's "reality." It could plausibly happen in the real world.
