It's rare that I use another fantasy race unless the concept is specifically intended for it. I play a good amount of D&D and the bonus feat and extra skill points are just too delicious to pass up, as is the fact that there's usually a great deal more variance in culture for humans than there are for the other fantasy races, who tend to have a few subdivisions (unless they're elves, but eating a -2 con penalty isn't something I'm often willing to do, other unbalanced racial adjustments for the superfluous elf subraces nonwithstanding.).
