This like this are now a matter of automation and tedious scripting - you could easily integrate dall-e into a platform/sprite game builder. You could probably make a killing doing something like a minecraft skin generator...

You could do fantastic, on-device 8-bit pixel art generators with clip and so the 80s and 90s spritemaps , and a high level gpt-3/ gpt-neo dialog or adventure generator.

If you use constraints wisely, AI-Dungeon and KoboldAI can produce fantastic adventures. I'm excited about AI- augmented have development coming in the near future. Transformers tech is going to diffuse into everything creative and will amplify the quality of games.
