Once both
When the dust finally settled, Tammy created a pair of characters, both nameless as of this time. One of them is a detective and the other is an antiques expert who works at an auction house.
Overall, it was a satifying afternoon of Chill 3rd Edition character creation, and I threw in an addition 25-minute quick session to show the players the mechanics and how they work, set at an abandoned farmhouse outside Winchester, Ontario. Lots of fun.
