The part of this that always confuses me is like nobody's aware gamejams exist, this has been a thing long before the LLM craze and people have been producing decent games on very limited timespans already, but people are forgetting how insanely high the bar is now, LLMs do not even remotely begin to fix the problem of your competition being incredibly stiff.
Just look at something like ludum dare and all the top entries (out of thousands of games submitted) are all usually quite polished given the timespan.
