You're talking about what's essentially a HUD on your glasses, which is neat and all don't get me wrong. But not something I can imagine playing many games on. At least... not games that didn't involve a cross between virtual and real space.

I'd honestly have much more faith in something like the Oculus Rift revolutionising the video game industry.

What I could see would be things like open invitation gaming groups putting up tags you can see in a city. So when you're walking around a city you can see if there's a group meeting up to discuss or play whatever in the area.
