I can't imagine playing Xortex (a game in Valve's 'The Lab') on a 2D monitor. It just wouldn't be possible to even come close to replicating the experience.
Valve also has a new product called "Destinations" which is basically creation tools and a viewer for photogrammetry scenes. One of their examples is Mars, with a realistically rendered model of Curiosity on the surface (which itself is based on photos from Curiosity). It's the closest I'll ever get to walking on Mars. And being able to walk around an actual-sized Curiosity is quite something in itself.
