1) The main character must be Cool!
(Why would anybody want to go around killing innocent people in order to pay a tennis coach $150 an hour to basically live at their house and sleep with their wife!?)
2) The setting must be Interesting!
(Otherwise it's boring! And there's nothing interesting about a typical modern day city!)
3) The missions must be Open!
(We play open world games for freedom, not to be constatly told “STAY ON THE YELLOW LINE!” like Rockstar does during a mission)
4) The open world must be Dynamic!
(...having everybody across the map instantly know how I behaved in Mexico does not make the game feel alive!)
5) The “side content” must be of equal value!
(Our time is too precious to waste a single second of it time with any of that tacked on “bring me 5 flowers” bullcrap!)
