Yeah, it's pretty much the best possible demo of the Rift's abilities. The Tuscany demo in the SDK is IMO not great for showing the full promise of the technology - everything is static and the level geometry means you never really get close to anything for the depth perception to punch you in the face.

TF2 has all of that and more. My score has taken a punishment, but it's just so damn enjoyable.

I'm also that ass on your team that's walking around looking at stuff in amazement instead of shooting the enemy...
