Well, I'm moving up to Fort Lame this weekend, and I play pretty much all the Bemani games, so I guess somebody still plays.
The IIDX machine has left, however. TnT still has an ancient version of Guitar Freaks, and DDR still exists (including SN). There's also Pump It Up to be played.

If neither of the above apply, you are normal. Congratulations.
