Why would you bother its gunna be bother. race 07 is 100 times better and it came out in 2006 .this ant a sim its a game ha
and rFactor, iRacing, rFactor 2, AC, RRRE etc are over 100x better than Race 07.
GT5 has different aims than Race 07. Race 07 is specifically for console which is more of a simulation platform. GT5 isn't meant to be full simulation and is specifically Console.
Therefore, it isn't easy to compare Race 07 and GT5 because they are meant for different target audiences. It would be like comparing Race 07 to a Banana. They are meant for different purposes and different target audiences.
