As every game store knows, MtG keeps the lights on, while the table top guys just take up space playing. If you do have gaming tables in the back, why always in the back?, make the boards an extra 18" long so people have a "side board" and a place to put their gear under so it is kind of out of the way. Not to push other peoples products, but the FAT mats are amazing! To get your tables up and running quickly a few of those mats layed out with terrain to match would look nice. Then if you sell the FAT mats to boot, win win.
Beer is always a good selling point for gamers, but that takes extra work. I always wondered if Kambucha on tap down in that Portland region would be a good draw...
Brilliant!!!
