I have a friend. He was been playing video games since he was 5, he is no 22. He never had problems with sociality. He is very social, very happy with his life, he had some relations (girls).
I asked him about some symptoms of mine and other peoples' (taken from here) and he responded negetively to all.
I, personally, think that it is not video games that take (som of) us inside the "zone", nor they trigger it. Instead, I believe, that the video games perhaps make it clear that something is wrong.
Looking a video game you suddenly realize the difference and it becomes clear that there is something wrong in the real world. Playing a video game for someone with DP/DR could be a chance ("chance" in a negetive way) to understand/see that he/she has DP/DR.
Anyone playing Doom (1993-2004), Quake (1999), Wolfenstein (1992-2001) game series?
