I do not know what all of them have to the game. I've been playing since release and can safely say that I am addicted to it: D What more could you ask for, expect at an open World Game, which has been developed (to load-Gen times so) for many years with so extensive primary and secondary missions ?! The graphics are good. The main missions are not perfect but entertaining. The side missions are just awesome. The moment when a hacker logs into your game -> BRILLIANT !!! Digital trips are just very funny and exciting: D Just the fact that every citizen has its own personality, I find awesome (always interesting things that you can read: D)
Even guilt when you have to play a game obsessively in two days through to then get excited unnecessarily on a great game. Expected not always 100% and screwed times your requirements down!
I can only say so much: I have recommended it to two other people and who are just as enthusiastic about the game as I do;) Holt it to you, it's definitely an entertaining next-gen game replayability!
