I think this discussion highlights something interesting:

Our society is moving towards a more one-dimensional conception of enjoyment, or in other words, "base fun". Not to say that simple fun is bad, but I think it would be a shame if life enjoyment were reduced to straightforward fun and nothing else.

Meanwhile, I’ve spent the last five weeks poking at an MNA and fluid dynamics solver for Minecraft, of all things. That’s the kind of fun I like. It’s what you’re looking for, isn’t it?

Heavy use of AI, of course. I’d never have gotten anywhere on my own; I’ve got my hands full just playtesting everything.

But you're

* not selling it

* not expecting to get the attention for it that someone would get from e.g. porting Sonic to the Amiga.

That makes all the difference in the world.

It's a game. Fun is the literal definition of what I'm looking for

Yes, but tastes differ as to what fun is, and endless banal dialogue in Claudish would, for most people, wear thin as quickly as smalltalk with chatbots.
