I don't play video games very often, but there was a period a few years ago when I had had several dreams where I was in the game Deus EX. It was still animated graphics or whatever, but I was actually in it. I didn't become lucid. I also had dreams where the dream consisted only of a 2-D image of Tetris or Minesweeper, not me playing the game, just the game going on as if that was all there is in the universe.
