TS, try to get your cc near a college, e.g. Taman Connaught area (Near UCSI, no don't open there, we've got more than enough nice CCs already)

make sure they have very nice chairs, have very popular internet connection (Unifi, and should state in front of the glass entrance)

must have contract with flying spaghetti monster (so that your customers can get perks and a better reason to go to your CC) (for games like League of Legends, etc.)

or Asiasoft (for MapleStory, etc.)

I'm not sure about the CC management system, most CCs i go to these days have the same managing system, i mean the games and entertainment menu, etc. just not sure what you call it, I forgot.
take examples from FTZ, Orange, Coolge, Tbun etc.
