To the defense of Rush, in my opinion the writers of the horror expansion are to blame mainly. This edge screams power gaming, basically that is its purpose -- so if it's in the book, it's natural that players will want it.

As a GM, I would totally discard this nonsense edge, and if I wanted my players to start Seasoned, I would just say so.

This post is not about arguing the GM's decision, it's a direct criticism of the edge and its creators.
