Well, I made a club for my snobby rich ladies to get together and experience the refinement of the city via admiring art and live performances, I have a club for my lazy and food-loving sims wherein they order pizza and pig out in front of the tv, I have a couple of gangs (basically they're color coded and all fight with each other), some bowling teams, a parenting support group (A.K.A. tired moms and dads going bar-hopping), some goody-goody kids who gather to play games and do homework and some mean kids who torment the goody-goody kids, a group of kleptos that just swarm a place in droves and snatch up everything they can because they can't all get caught (right?), the ornery elders who like coffee, naps and yelling at the local brats, my dance crew that goes around to every club to flirt with whoever looks good, some makeshift "bands", the friendly neighborhood evil masterminds, the gamer geeks, a group of good vampires and a group of evil vampires... I didn't realize I had so many clubs, lol
