I dropped a link to this solo-RP on the Solo_Roleplaying subReddit. I'm looking forward to continuing my solo efforts, although perhaps effort isn't the right word. It's been relaxing and fun. Years ago, I would have found the notion of solo gaming laughable. In truth, I only became interested in it in the past few years, as I continued to see its popularity explode on the internet.
I've done a fair bit of reading about this hobby: Mythic GME, UNE, lots of blog posts, lots of actual plays. I found Four Against Darkness too fiddly, although in fairness I haven't given it a fair chance.
This current solo I have named Endless Rime and have set it in the Upper Paleolithic, roughly 35,000 years ago.
