Do you have enough space for a dance-party? I know that I like nothing more than to impress some hottie with my Street Fighter prowess, and then cut a rug, and have some drinks. Secondly, a dance-party night can bring in folks who are not super keen on the vidya, but then see other folks playing and living, and laughing. Then, someone like me fleeces them in a winner-stays-loser-pays grift.
