Duskthrone had AI battle sprites, which isn't a big deal at all, other than looking inconsistent at times. But I don't think the game had AI text. It might be a translation issue on Dev's end, if he used Grammarly or a similar program to correct the grammar.
There's no issue with the AI sprites since the game has the ai-cg tag, right.
I guess the smell of AI text isn't as obvious as AI images for most people (including the developer of this game who barely tried to conceal it), but it's still very obvious if you talk with LLMs a lot. AI-generated prose and dialogue, regardless of the genre it's trying to approximate, has a distinctive and standardized tone which no human actually uses unless they're writing a perfect high school essay or advertising material. Adjective choices are too precise. If you look for it you'll notice the same dramatic beats repeated again and again in every paragraph contrasting this and that. The dialogue is unnaturally "perfect" and soulless in this way most of the time, but at other times (particularly outside of dialogue) it's improperly copy-pasted grammatically incorrect nonsense revealing the author's true English ability.
Grammar checkers don't entirely rewrite sentences and insert em dashes, do they? I'm confident the vast majority of text in all 3 games was written by an LLM given vague executive direction to write the next scene or whatever. It also feels like AI was used extensively during planning, given the pacing of the plot. Anyone who has tried to roleplay with an LLM before should be aware of the dreamlike episodic limits of its ability to remember information and keep track of state even over short durations, a limitation a human using a grammar checker or translating from another language wouldn't have. Conversations trail off aimlessly, which is common to encounter when LLMs run out of ideas and aren't sure when the user expects them to stop generating text. Everything about the game is astonishingly generic, it's actually hard for a human to come up with something so entirely devoid of uniqueness and soul.
Below I've asked ChatGPT to rewrite the above two paragraphs to demonstrate my point:
Oh, and the weird nonuniform ellipses everywhere in the dialogue, that's probably from the developer lazily spamming the chat prompt with periods to get the LLM to generate more text.
