It's a fantastic tool to discover things!

As soon as you start going more to the niche side, it gets super specific. My day jobs is RTL design, doing digital circuits, and my top 1 niche recommendation is MHRD, "a game in which you design various hardware circuits in a hardware description language."

MHRD is pretty fun. The implementation is a little janky (it's written in Java, the interface isn't accelerated, the leaderboards are a little broken), but as a game it's basically "starting with a NAND gate, build a processor from scratch, using components you've built in earlier levels". Honestly, for me, it was like a refresher of the 6 month processor design course I did in my CS degree 20 years ago.

You might find it a little simplistic given your day job, but for anyone else reading, I found it really fun.

Side note: If you like MHRD and want something a little less real world and a little more video gamey, try TIS-100, which might be the single best game on Steam.
