Building The Ideal Geek Gaming Center?

MongooseCN writes "After seeing the popularity of multiplayer gaming and the desire for fellow geeks to find better means of socializing, I've decided to open up a geek gaming center. It would allow people to play games together in the same building, and to talk and hang out too. I know there are a few of these places already, but few of them have taken into consideration what people want to see in these centers. Most of them open with only the owner's opinion of what would make the place fun. Some don't even allow people to hang out, since they charge by the hour. So what I want to know is what the /. community would like to see in a place like this. I want to start a gathering place for other like minded, techno-savvy geeks. What games, gaming systems/hardware, etc should it have? What would make it a fun place to hang out and meet other people?"
