Lol, srry, I tend to let people make their own techniques, and just explain the idea behind it. Ok, people are doing this already. What they are doing, is recognizing dream signs, that is, common things that are universal to a dream, a shoe, a hair pin, or in your case, a specific video game. Now, every time in RL when they come across such sign, they do a RC. Eventually, this "bleeds" over to the dreamworld. Except that it is not "bleeding" over, but is rather a result of conditioning. SO, if we use this understanding, we can make it "bleed" over much much faster. Ahem. So here is the tutorial.

First: Identify a common dream sign. In your case it is video games. That is sort of general, so I suggest you see which game it is, and identify the scene that you normally see in a dream.

Second: Start playing the game.

Third: When the scene comes up, in response, say aloud, with force, "This is a dream" whilst feeling that the world around you is a dream.

Four: Repeat the Third step six more times.

Five: Go eat something, go run, have sex, distract yourself.

Six: Start playing game again to test whether you have conditioned response( you are re-exposing yourself to dream stimuli).

Seven: If conditioned response has been set, there should be an immediate response to the situation just as you practiced

Eighth: Every time you play the game, make sure that you do not fight the response when it comes, but rather embrace it, to keep making sure it "sticks", so to speak

Nine: Go to sleep, and focus on recall, and report back to me results.

Any questions?
