This article's note about game making 100% wrong, games are highly "complex" and there's a lot of iterative refinement and experimentation that is involved in "finding the fun." You can't just throw a pot of well liked mechanics together, because without balance or the right context it'll be flat. Also, unlike music where people often like something that's mostly derivative with some slight stylistic tweaks, if a game is derivative people will just keep playing the thing it's derived from.

The attitude of just leaning into your creativity regardless is good though. I know a bunch of local metal bands that kinda suck, but they grind away at it because it's fun and they love metal, not for some hope of a future payday. They don't care if AI makes better music than them, it's a community/personal expression exercise.
