I can't offer you any castmates yet but have you considered tushanshu? We're a small/slow game with a lot of plot, some horror elements, and equal chances to largely ignore the plot and do SOL if you prefer. AC is 15 comments per month across 3 threads, with the opportunity to buy IC rewards with more, and everyone backtags into the sun.

I would LOVE to see either Sebastian or Alistair in Tushan, although from what little I know about Stargate I think Daniel would also get along quite well?
