Actually, playing video games near bed is a bad thing, especially if it has flashing/explosions/bright colors. They've said repeatedly that it keeps the mind awake for a while afterwards (even more so that seeing those on TV before going to bed, because you are interacting with the game). I can vouch for that, too. I have had nights where my mind just raced for the first few hours, just going over stuff in the game, all the time my body is asleep. I literally have to get up and read a book or something similar to "clear" my mind of the game.
