At the risk of sounding like a broken record... /cough

I can't offer you any castmates, but tushanshu hits all of your preferences I think! We're a small/slowish game with lots of plot and the opportunity for SoL, whichever way a person's preference slides. AC is 15 comments a month across 3 threads max, with more activity earning IC rewards like items from home, plot advancement, etc. There's no history section on the app, so minor characters are golden as long as they can fill up a personality section and don't have an overwhelming amount of headcanon in the app.

We have a TDM up here if you're at all interested!
