You don't need VR goggles to see the world differently.
In Mirror's Edge, your first-person view of the world is overlaid with new information - any red object is a potential runnable path. After you've played it for long enough, you start to see the real world that way, too. Whenever I'm out for a run, in my mind's eye railings, low walls, ladders and platforms all pick up a red highlight. It's fun.
The effect is even stronger for games you've played in the real world. Back when I was doing a lot of geocaching, I'd see hiding places everywhere, even when I wasn't playing. After doing a lot of Undercover playtests, I'd see potential dead-drop locations, and be aware of who was watching me in a way that I'm not usually. Citydash players tell me that afterwards they're extremely alert to people who are wearing hi-vis vests (the uniform of the game's adversaries), even long after the game.
Real-world games write their stories onto the real world, where you spend most of your time. They make life more exciting long after you've finished playing them.
