Yep, there’s some pretty stellar solo games out there (1000 Year Old Vampire, Ironsworn, Five Parsecs from Home), and most popular systems already have solo RPG adaptations that people have worked up. There’s a number of benefits to solo RPGs, though obviously the big drawback is the lack of interaction with others. I play both solo and multiplayer ttrpgs, so it’s not a matter of just “not having anyone to play with”, I genuinely like things from both experiences.

• Play anytime you want on your schedule, don’t have to herd cats trying to get potentially unreliable players to grace you with their presence. • Play what you want to play, experiment with new systems or genres that maybe your regular gaming group won’t play. • Great practice for GMs, you usually have to react to unpredictable, random results with no pre-determined story in mind and make it make sense to yourself. It really helps with your improvisation skills. • If you develop any random tables or content for yourself (settings, stories, npcs, etc), you can just as easily use those in your multiplayer games. • You make the rules. In multiplayer games most everybody has to agree on the rules (or you’re at the mercy of the GM’s interpretations), in solo RPGs, you can homebrew or reinterpret whatever rules you want to.

What defines a solo RPG? Being an RPG where you only have 1 character? Dark Souls would fit into that. So would The Witcher and Cyberpunk. Hell, Baldur's Gate 3 could fit into that, since you could play it with just 1 party member (it'd be hard as shit, but still possible; you can solo the originals, too, and those were balanced for 6 party members).

Practically all but JRPGs could be played as solo rpgs.

There's a ton for the SNES and NES. Chrono Trigger, Final Fantasy 4, 5, & 6, Breath of Fire 1 & 2, and Secret of Mana for the SNES alone. That's not even counting the NES, which had Dragon Quest 1-4, Final Fantasy. Then there's all the translated stuff. Check em out. What I listed is probably enough to keep someone busy for a year. Emulation's not hard at all to set up these days.

I've looked at a couple. I think you need a game system which catches your attention if your not particularly creative. They generally give you good prompts and have plenty of generators/ oracle's to guide you.

Check out Ironsworn. I believe it's free and it's generally very well regarded. I've not played it myself yet but I've read most of the book and it seems very well put together.

I haven’t but have looked into them a bit and have quite a few friends who play them. I don’t think you need to be extremely creative from what I hear but rather get really into your character
