It axes and wanes but stands eternal. 25 years and going, over half of that time online. PbP is a unique relic leftover from the early 21st century. My own interests have shifted towards live gaming online wit Discord and roll20. It is a more immediate satisfaction. I also lost the heart to guide a story, what after that travesty of a supernal horror story I tried to run that ended with a player rage quitting. Indeed, I have always ever been in conflict with the "storytelling" style of Ars Magica, though I see the role of a story GUIDE to be more of a committee chair than a railroad driver. PbP is really really slow though. I am still playing one of Fixer's stories.
Andorra is much larger than any one gamer or SG.
Keep playing. Do what you want with Andorra. The saga is yours. I am still here.
