So I have another idea..... :/

I started thinking about the rules I wrote the other day, and came up with some stupid setting for it. This one is post-apocalyptic dieselpunk fantasy XD Basically, there's some big event centuries ago, and humanity has managed to claw their way back up to diesel engine levels of technology, although they still regard it as magic. There is magic in the form of..... I dunno, radiation or something, and the fantasy "races" involved (vampires/undead, orcs) are a result of mutations. They have mech suits and armoured cars/tanks and short ranged rifles and SMGs.
