Thus far I've only played one GM-less adventure and it was a solo one. After rolling up the character and discovering what kind of settlement I was in and what kind of adventure I was getting my self into I set off into the trackless hills. Unfortunately my cleric's survival skills were lacking and after getting lost several times I made camp for the night only to have a goblin crush my skull. That may not seem like a grand adventure but I actually had a lot of fun. I'll definitely be trying this again next time though I hope to actually make it to the dungeon.
