The video game market was already flooded before LLMs. Now, it's much much worse. I'm not sure that "AI" vs. "no AI" is really the right filter, but I do understand the need to filter out the chaff. There's too much content, and too little time. Even for something that you love, there's more out there than can possibly be managed or enjoyed. This problem will get worse.
On the flip side, the purpose of Steam is to find new users for CSGO and DOTA2.
