I'm currently playing through Dragon Quest VII: Reimagined (and reading Operation Bounce House) and so not likely to get any solo play stuff actually posted to this blog until at least next week...
BUT I just saw that Bundle of Holding is having a Neon City Overdrive Bundle for $5.95 for the next 18 days.

I've only played it for a few sessions but I love it already.
If Cyberpunk isn't your thing, just keep in mind that the whole system, which uses Tags and Subtags (Trademarks, Edges, Flaws, Gear, etc) linked to a Action vs Danger dice setup, is actually able to play pretty much any genre you want.
It's pretty easy to tweak it per genre or per campaign.
Fantasy: Ancestry and Class can both be Trademarks with Edges representing foci. Goblin [Cave-Born] Warrior [Swords, Dark-Fighting] vs Elf [Studious] Trap-Maker [Poison Traps]. Then other Trademarks could represent multi-classing, key features, whatever.
Supers: Each Trademark could be a power-subset with each Edge being a signature move. Super Strength [1-2-3 Punch], Flight [Super Sonic Boom], etc. The assumption would be that the default power level would make encounters with mundane enemies/situations require no rolls or only rolls to check against collateral damage, rule-of-cool, etc.
Horror: Honestly wouldn't require any tweaking but you could emulate worsening situations by having Danger Dice increase as the zombies, infection, alien-robot-death-killers, etc grow in number and power to show a loss of control.
You can hack on types of dice (e.g. Dark Power Dice that add to your Action Dice but if they are the highest number represent a descent into cursed power, Lycanthropes maybe get Beast Dice when in transformed form, etc) or allow for more Edges to represent a wider "skill" list. All sorts of things .
One of the ideas I have is to maybe hack it together with The End of the World RPG (still available as PDFs on DriveThruRPG) in various ways since I think the two share just enough conceptual DNA that you could bring over stuff like Stress to NCO-style systems without stopping on the low overhead vibe.
