I just picked up Heart of the Machine. It’s a turn-based RPG/4X/city builder (which apparently also includes multiversal time travel) in early access. You play as a rogue AI trying to survive in a dystopian cyberpunk city. If that sounds insanely ambitious, that’s because it is, especially for a solo dev. I played the (surprisingly full featured) demo and got immediately hooked. The different systems seem to tie together surprisingly well; the RPG elements provide a bit of drive to engage with the strategy side, and choices influence how you build out your tech tree. Probably not for everyone but the demo is free and worth checking out if it sounds interesting to you.
