While the specs of the machines are important a cafe should provide a more versatile packagethan just powerful PC's.That's why we have consoles at cafes now.I think that regardless of the specs on the machines if I come to a cafe and I don't get to sweat because the cafe don't have enough machines or if i real hungry and can't concentrate then it ruins the experience. Comfort and safety is a big issue to me too. If the cafe not properly secured then I won't feel safe sweating till late in the night. Gameing cafes are your homes away from home were you and your friends can have some good clean fun together and anything that can add to that experience would make me value that cafe a bit higher. There would be no point if the experience wasn't better than playing at home.
And it would come in 3 varieties!!! like whole wheat, whole grain and plain..OMG IT COULD BE CRIX!!!
