I played solo twice, and I think the game is good solo. But to be honest I mostly ignored the solo rules, and made my own version with Mythic GM Emulator. I also made my map on the fly with a personal randomiser, and I ignored the lore and almost everything about the setting of Ravenland.

I never made it far because between running games, painting miniatures, prepping and finding time to play solo has been hard. Plus, I'd really like to try The Walking Dead RPG solo at some point.

My recommendation is, play with one character and two or three npc companions, flip one of them to PC if your main character dies. Be kind to yourself. That should get you going, I'd say.
