I'm also in the process of doing a game room. It will be mixed pins, vids, air hockey, foosball, etc. Besides the sound one thing that concerns me is lighting. I would be concerned with lights reflecting off monitors and glass. For me, I'm going to be concerned with reflections off pinball glass too. I've read where some people paint their ceiling black or hang black fabric to prevent reflections. Also, too bright a light distracts from the arcade screens / pinball lights. I plan to hang lights directly over the air hockey and foosball tables to light them as needed (similar to a pool table light).
