What you are asking for also flies against how current games are licensed so you may encounter some hefty investment in the order of about 10K USD per game station.
Have you done the math?
I have the opportunity to help establish an Internet Cafe. It's main audience are established gamers, but I'm looking for a menu that will allow more casual walk-ins to comfortably browse the wide array of games.
As a minimum, I'm looking for a friendly GUI (it's fine if I have to tweak it), and the ability to add descriptive text to let customers know what they're looking at. The ability to sort games into custom categories is also a must have.
The ability to have "Featured" and "Most Popular" lists would also be great.
