KR games being turbo games depend solely on people's willingness to use their knives and powers~ Theoretically speaking, any game can end before D2 IIRC... Well, maybe not TK, and even then it is a maybe~ Either way, from powers alone, you can get up to 4 deaths per night, not counting stabs, so... It can be pretty fast paced for sure! XD
I have 0 ideas~ I'd go with a normal game, though reducing the Sorcerer's Max HP to 4 in order to try nerfing the role. I've been meaning to test this change for a while now, but I haven't hosted in a long while... >.>
