Not sure how I'd set it up, but I was considering solo-playing one of the Pathfinder APs. That's a massive undertaking, however, and difficult to keep entertaining even with a full cast. Doing one of the one-shots is a more feasible, smaller-scale project that might see completion.
I'd like to do it either as written, fiction-like summaries, or as an edited YouTube video. The issue with YouTube is my appearance and voice. I can mitigate appearance by simply not showing my face. But my voice... is more complicated. I need to work on it; I like it, and it doesn't give me dysphoria personally, but I'm hard-pressed to "feel" like myself on the Internet when presenting myself to the public because it is a distinctly "masculine" voice.
