What video games do you play to lose weight?

I just load stepmania up and put it on endless mode on hard, then I play til I drop or run out of breath.

I played today actually because it was too hot to cycle. I have an insane amount of songs that I'm willing to share if anyone wants. I think DDR is definitely one of the more intense games.

I have two of these pads that I bought a couple if years ago
