Hi! You ain't going to get rid of me too easy, Gary.
You thought right. Modability was one of the design goals for Perdition's Mouth and the company stance regarding modding PM is... go nuts! I for one have been counting days to the moment some silly bugger to commits the ultimate heresy: modding dice into Perdition's Mouth!
When you get the delivery, rip it open on that very moment, give the game a bit of play time, and then, let's get this party started!
