If you want an uninterrupted gaming experience, moving your game room to the basement is the way to go. With no more housemates complaining about the noise, you are free to set up your materials as you see fit. Add in items like pool tables, foosball sets, dartboards, gaming consoles, or arcade and pinball cabinets (if you have the cash for them). You can even include a wet bar so you can enjoy a shot or two while taking shots with the mates.
