I'm familiar with Delta Green just don't like the every character has to go insane eventually. I'm like Kirk. Don't believe in a no win scenario. Maybe combine some elements of Conspiracy X with Delta Green. Have to think about it.
I've recently gotten a copy of Conspiracy X 1ed RPG. Love the backround, original system seems ok but I really prefer a % based system. I was wondering if anyone had already done some work on this type of conversion/ game type.
