So this is your argument?? Forza horizon de-throned GT5? What is so great about de-throning a 2 year old game??? Why are you so suprised that any new racing game that is released now or in the future is better than GT5? GT5 was in production for 5 years and then the ps3 wasnt even released yet. If Forza horizon wasnt better than GT5 then the developer failed miserably because GT5 has been released for 2 years now and microsoft have plenty of time and should able to improve on it to make a better game then GT5.
Lets compare GT6 to the next Forza game when they both are released on the next gen console.
For those who says GT5 is "a boring game" then obviously this game is not for you. The box does say a driving "Simulator" so i dont know why you guys are complaining. You know what to expect. If I wanted a simulator i will play GT5, if i want to play arcade type racing i will play need for speed or Forza, and if i want to jump with my car and shoot turtle shells i will play Mario Kart. Something for everyone.
