Oh, so you mean what happens after a stretch of Portal 2, and you notice and enumerate how many surfaces in your domicile are portalable?
Or how a four story building with some nice ledges and loose brickwork looks climbable after playing Assassin's Creed?
Or how the broken parts of a sidewalk are the equivalent of gaps in the world for 2D platformers?
How after a protracted session of Prototype, you have to wonder if you should eat people for their knowledge/have the urge to try and run up buildings and kick helicopters out of the sky?
Or how you could hang from a ledge and silently drop down like the goddam Batman after enough Arkham Asylum?
How about when a Guitar Hero song comes on, and you instinctively move your arms to the "holding a small plastic guitar" position, and see chromatic lines of notes and chords scrolling past on the ground before you? Does that count?
Maybe it manifests itself after playing Just Cause 2, and you know that you could jump out of your car down the highway, hookshoot to someone else's, surf atop it, shoot out someone else's tire to stop up the cops who aren't yet on your trail, throw the guy out of the car, and get away scott-free?
Still, it's nice to have a name for it, if only for casual conversations sake. "Aw man, I'm totally tripping on this Game Transference right now. Everything looks smaller than me, and I have to remember not to try and roll it up! Damn you Katamari!"
