From the creators of "He's so good he must be using cheats", coming this winter straight to streaming services: "He's so basic he must be using AI".
It's not really about being basic. It's about a consistent pattern. Anyone who has used a LLM for roleplay can attest that unless you really tell it how to speak, then it will always "hesitate" when it tries to be suggestive.
"I can tell you're rather... excited to see me"
"I'm sure we can find something more... fun to do"
"Some part of her was nervous about the situation, but another part, a bigger part was... looking forward to it"
Same happens with LLM arching their chest towards the hand, arching their back when having sex, fluttering their eyes, eyes half-lidded in lust, their pussy clenching in need around nothing, repeating "Please... I need it...", etc. Bunch of expressions and words that some models overuse when it doesn't know better.
If this game's creator didn't use AI and is, as you say, "basic". Then all the more reason to point this out to him, so they can improve and be better than "AI-level basic"
