My son was gifted an old Mac from his grandparents. It only supports OSX 10.13. I’ve been able to make several games that he genuinely likes (7 yo) Opus built them on my workstation and then pushed them to his computer and tested them over SSH. It handled all the asset creation or collection from CC0 licensed sources. I believe everything is built on the Godot engine. It’s really amazing to me. I don’t know what it would cost me to get someone to build custom games on a long deprecated computer architecture, but I paid Anthropic $20.

I don't think it is vague in the slightest. Take the most simple examples, how many LLM's have you tested making them? There are stylistic choices pertaining to games that is well beyond a 0/1 reward. Even something as basic as breakout or flappy bird can have wildly different quality between models. Yeah, you could call this animal on a bike benchmarking, but I don't think it is. IMO the problem space occupies an interesting area where you can ignore the pass/fail and focus on the actual level of the model to do something beyond that.

I doubt the OP meant something like creating the whole tech stack for WOW.
