Vantage is a great solo card game but it’s a bit expensive at $90. I really like it. Great game play loop and a fun way to use your cards while exploring. There’s also one deck dungeon for a lot cheaper. It’s not my favorite, but I play it in hotel rooms a lot because I can pack it easily.

This is a low barrier to entry solo game that is 1) free, and 2) it’ll let you know if you like this style of gaming.

For solo RPGs, I have gotten a lot out of using the Mythic Game Master Emulator with all sorts of games. I’m working on Coriolus right now, but I have had a lot of fun with simpler fantasy games like Knave and Maze Rats.

Starforged is great, but i got that on sale.

This is great for solo gaming:

So is this, even though it’s about PbP games
