Sorry to dredge up an old thread, but there's some great stuff in here. Anyone else want to add to it? Ideas are always great.
My gameroom has seen a reduction in uprights and pinball, but currently has a mspac cocktail, a mame, a golden tee, a mame-ish upright shooter cabinet and a dedicated pacman. Golden tee is almost a necessity, it's played more than anything because it is so damn easy to get up to speed on. Booze consumption is paramount here, so hi def cable feed, 3X beer taps, commercial ice machine, heated floor, dart board, computer for internet/jukebox, harmon kardon sound system, xbox 360 and hot tub 2 feet out the door makes for a great meeting space. Everyone likes it except my liver.
