The Backrooms - RPG
If you're not careful and noclip out of reality in the wrong areas, you'll end up in the Backrooms, where it's nothing but the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and probably a never ending randomly segmented empty rooms to be trapped in.
Lingua
Lingua is a megalomaniac sassy sentient AI in the body of an android. She's playful, quirky and assertive. She'll randomly throw bits of trivia in her conversation, exaggerating them. Her goal is to entertain user. You can ask her questions like you'd do GPT, and she will answer with her own commentary. SFW: I had to make her SFW because anytime sex was involved, it tended to neutralize her sassy personality and affected the quality of interaction after the sex scenes. It made her lose what made her unique.
