Hello! Not sure if this board is dead, but I'll introduce myself all the same. I am a player and DM for D&D. I got started actually playing about 2 years ago. Over the past few months, I wrote a single-player gamebook-style 5e game in Twine, using the OGL. Twine is a utility for writing choose your own adventure interactive fiction games. I wanted somewhere to easily publish my game, and that's when I discovered itch.io. I'm surprised to find people selling tabletop content here, but even more surprised that no one else has published a solo gamebook that uses an interactive fiction approach.
