I enjoy working on my pins as much as playing them so I actually havent put anything down in my gameroom. I figure if I put carpeting in, Im bound to drop paint brushes, iron or God knows what else. I will probably put in tile one of these days but for now, I havent put anything. Just concrete. Not to mention carpet does get nasty quick. I do flooring as well for a living and you wouldnt believe the mess thats usually under carpeting. How about a nice engineered floating wood floor? Theres tons of choices. From oak to bamboo or even tigerwood. Not hard to install either and looks nice. It will scratch if you slide a pin across it but you could get felt sliders and put them under your legs if you like to move them around.
