The rules are very simple (totally didn't just steal a german forum game for this):
You give two options like this:
PSX or Saturn
The next person to reply has to answer, with an optional reasoning, to continue the example:
PSX, because Ridge Racer runs better.
Then that person also has to give two new things to choose between, and the cycle continues:
NES or SG-1000
And with all of that out of the way, here's the first choice,
DanceDanceRevolution or Pump it UP
