The thing is, that even though this is a good store, I will not play there. For me its hard to just show up to the store and sit down where some group is playing and insert myself into there group. I feel like an outsider. This goes for any game store I have been in.
To get me to come game at your store I need to feel invited to play before I come in. I played my first 4th edition game at the gamersgambit and it was a nice experience. While shopping for some DnD minis and stuff I was told they where doing some 4th edition demo games and asked if I would like to play. They did a good job of making it an event, they had a BBQ and lots of premade character sheets. They should have had someone organize a marshaling area because I did not know where to go to get into a starting game. If you invite me to game at your store I will buy some gaming stuff while I'm there.
