Probably would visit. I am always up for checking something out.
I like all the comment's on how this would be the least aggressive clientèle. Gamers are people, and just as many fly into a rage for stupid reasons as any segment of the population. I actually think you would see more aggression then normal, as now you are combining drinking and competition - think sports games, we all know fights never break out over sports. Probably one of the reasons to limit it to 40 or 50 people, other then cost that is.
