Invest in wacky and unique gaming room furniture to customize your gaming setup.  For a gaming room centered on vintage gaming systems, try hanging Donkey Kong-inspired shelves or using a glass coffee table with an oversized game controller as its base. A bright yellow Pacman-shaped bookshelf adds to your vintage game aesthetic.
Use multi-color lights to give your gaming setup pazazz. Install color-changing LED lights in white storage cubbies and store your gaming system, controllers, and games under them, creating a display unit. Opt for a moon-shaped neon sign to add a blue glow to the room when you turn the lights out. Also, consider investing in a piece of multipurpose furniture that doubles as a couch and bed for late-night gaming sessions.
