I've gotten some of my coworkers involved in fantasy NASCAR. Ridiculous, right? But you pick your drivers, you get points based directly on NASCAR scoring (so you know exactly what you'll get), and during the Chase, you pick just one driver for the whole "playoff" season. It's turned some people from a "they just make left turns..." to a "that was a wicked maneuver when they were racing three wide and he got loose through the corner!"
