Aristo, please leave the trait system at the door. I for one don't feel particularly inclined to have my imagination restricted by arbitrary traits that I have to take 2-3 positive and 2-3 negative ones. Traits allow the GM to exert much more control over what happens in the game, and possibly 'too' much control - I have had very bad experiences in the past with GMs over-controlling things like this.

But that's just my tuppence on the matter.
