I generally prefer to play with dim lights or lights off and just the glow from the games lighting the room like the arcades...We have can lights in our gameroom ceiling along with a fan in the center...my preference is to play with the light on the fan on and the rest off. I don't like having super bright lights on above the games as they sometimes create glare...I prefer to have the arcade atmosphere as opposed to the "shop" bright lights on when playing...Most newer games have plenty of light on there own with no need for added lights!
