I have all editions of this game, but only ever read and played the 1st and 3rd editions of AEG's roll Trait + Skill keep Trait. I know the 2nd edition twisted the roll and keep system so that you kept the Skill this time around. Does both the rules and supple,ments for the 2nd edition allow me to ignore this and still use T+S keep T without it screwing up the game?
