House Rules or Revisions in Grimm RPG Posted April 30, 2010 True I used a different terminology, but that is not the point. Personally I don't like the "Talent" rules and the Iconic Trait rules. That are just to many little special snowflake rules. The goal of the house rules that I supposed and the OP are to reduce the number of special rules and to have a single and simple system. I run the game twice at a con and as a one shot and I that players often had problems remembering and using the Talents and Iconic Traits. Even character creation took longer, because we had only one rule book and everybody had to wait for it to flip through it and read the talents.
