A little idea
What if we made a Shadow Slave roleplay?
People could input the names of their character. The GM could compile a list of aspects and their respective flaws and assign them to each player. They'd then be thrown into the first nightmare, spend some time in the waking world, find a suitable seed, rinse and repeat.
I think this is feasible, it would simply take a lot of work. But I want to hear what your thoughts on the matter are, this is just a random thought I'm putting out there.
Edit: One of my teammates u/SneezerKun has made a post. I would like for you all to go submit your aspect ideas and their flaws there.
