As a gamer I recently keep having these thoughts about... an openworld game on UE5 with periodically generated maps / worlds and GPT enabled NPC.

So basically in-game AI characters with the capabilities of ChatGPT and co. From just conversing with them all the way to game mechanics, such as cooking, being run with an AI in the background.

You pickup any kind of food items, throw them in the pot, the AI analyses the content, suggest the dish or dishes you could produce in RL with the pots content. You select a dish, start cooking, AI calculates the nutrition you would get from said dish based on the quality of the food you've added to the pot.

That's just an example.. follow down this line of thoughts and you'll be like "fuck me, give me the game".
