Also, to the point about rear-projection TVs, obviously you don't want to pause a game and leave it that way for an extended period of time. However, it's also worth noting that the main reason why they don't recommend video games on those types of TVS is that even if you are constantly moving around, there is usually graphics on the screen that remain static for an extended period of time, such as your score in a Mario game, or the instrument cluster for most racing games. Those images can be burned into your TV, even while playing the game.
