Ludic = of or pertaining to play
Proxy = substitute, representativee
Ludic proxy = game-induced deja vu. Take these images, for example:
Image of the Prometheus monument in Pripyat as portrayed in the game STALKER: The Call of Pripyat.
The Prometheus monument in Pripyat, in real life.
Have you ever been so engrossed in a video game set in a specific location that you've never been to -- that when you do go there for the first time, you feel like you've been there before, you know which street to turn on, you recognize the architecture and layout of the city?
My play Ludic Proxy is about (among other things) the distortion of reality through the lens of technology and memory.
