Well, I looked around and found another post that talked about what seems to be the mutations changing on your character all the time. That pretty much kills it for me. I'm ok with giant chickens toting machine guns and wearing pilot goggles but they crossed a line there with the ever changing mutations. I supposed it does have a certain comic effect when you don't know what you will be armed with next encounter but I'm not willing to shill out the cash to find out. That and the idea of there being (albeit optional) booster packs for the cards says I'll probably be just fine skipping it.

That's alright, I've got mutations in my current game world anyway. My players are great and we almost always have a real gut busting laugh at some point. Hehe, got a Dwarf that can climb but every time he tries the player fails his roll and he falls. He's on the verge of developing a phobia
