I wanted to share something really cool from our currant Call of Cthulhu game. I'm not running the game, The Professor is. He, like the rest of us, was new to the system when we began, but that has not impeded his ability to GM. So far the game is absolutely awesome and part of it is the small things like his NPC Cards.
The concept is simple and certainly not a new one, but there is a reason this has been around for a while... It's a great idea. The Professor's execution of the concept is flawless. He lists pertinent information to the character like their name, nickname, and a Fraternity or Sorority if they belong to one. Then he gives some key biographical notes like where they are from, what their major is, what clubs and/or sports they are involved in, etc. Finally he lists character traits and events that have become clear as the PCs have interacted with them. For example, Ruth has proved untrusting of the PCs every time they have met her, Beth has a short temper and constantly yells, and Bobby beat the crap out of Revil's character, Kenneth.
Perhaps the most important feature of the card is the photo. Ever one for authenticity, The Professor has gone back into archives of old yearbooks and pulled actual student photos from the late 20s. It's a great touch that makes each NPC seem that much more real and gives each NPC card a yearbook-ish feel. That works really well as our characters have gone to old Yearsbooks as important sources of information on various persons around campus.
NPC cards like this are easy to make and definitely worth the time and effort. They help yours players connect with the various important NPCs and provide them with a quick reference guide to the pertinent facts about them. If you are playing a CoC game, particularly one set at Miskatonic University, you will want to also follow the Professor's lead and lean heavily on old yearbooks from the 20s and 30s as a resource of both pictures and great information about the time.
