"You might also be interested in "Beholden".
It's a game based on "Beloved". It basically switches the roles, and adds another twist: You're a deity.
And here is the big list of solo RPGs if you want to dive deeper into the rabbit hole: http://dieheart.net/useful-stuff/solo-rpg-resources/
You could use Mythic's GM Emulator to run any RPG with no gm. Here is also a list of good resources for gm-less play
Mythic is popular because it was one of the first GM Emulators. (emulator being a misnomer because you can't actually replace a GM/player in solo-play; you are both).
There have been many others oracles/engines since then that have refined the process including GRGE, 9 Questions, Miso, etc.
You can find a ton of solo resources here: http://dieheart.net/useful-stuff/solo-rpg-resources/
Some Misconceptions We Need to Clear Up
Solo Role-Playing: The Essential Toolbox
Lone Wolf Roleplaying Google+ group
dieheart.net solo rpg resources
Scarlet Heroes - contains a simple system that is compatible with most OSR games and system-agnostic tables for generating props in any fantasy settings.
Mythic GM simulator - the originator, requires a fare bit of bookkeeping and is not as fast/streamlined as it's many predecessors.
www.rpgsolo.com - almost every tool you might need to play in one interface. You can create a free forum account which opens up even more, genre-specific options (like classic fantasy, sci-fi, superheroes, etc.) plus you can save your notes/progress.
The GameMaster's Apprentice Base Deck - for when you need some offline help or you just want to speed play up
There are a number of these out there.
Mythic is the biggest one in the area, and IMO probably the most comprehensive. It's capable of directly working with other systems to allow you to convert them to solo RPGs, but it is a possible RPG onto itself. I recommend the red book edition as it includes a complete RPG; the blue book edition is just the GM emulator.
You may also like the yellow "Mythic Variations" add-on, as well.
Another popular one is Tunnels and Trolls. A free option is the CRGE and (Miso RPG - PDF file) [http://dieheart.net/wp-content/uploads/2017/03/Miso_RPG_1-1.pdf].
A more comprehensive list can be found at dieheart.net and this subreddit's wiki.
