I love Cinematic Unisystem. I use BTVS, Angel, AoD, and Ghosts constantly for hacking and setting up games. It's a robust thing, and I also beg and steal from Uni, especially AFMBE and Witchcraft, when needed. I lament that the last pondered Eden Studios release never came forth. I always hope it would turn up like some vapor-ware PDFs that eventually hit the internet.
Ghosts has a place in my heart for providing tons of medium-low level crunch entertainment.
