A huge part of what makes me a Forever GM is the fun of making stories for my friends to play out.
This is a map made with random dungeon dice, first time I've actually used them in 6 years ha ha =)
DnD 3.0, dnd 3.5, Pathfinder, Starfinder, Pathfinder Second Edition, Blue Rose AGE system, Call of Cthulhu, Adnd (advanced dungeons and dragons), it's all great.
What do you play, or are you curious about playing yourself? And yes, plenty of characters from stories have been built in game, and plenty of chars made ingame have found their way into my written stories!
