Challenges (licence, mission and track) are much more difficult than in previous games. For example, in GT5 you used to have only a few really difficult events (Grand Tour Eiger, Grand Tour Toscana and of course the Vettel Challenge) but GT7 is in a completely different ballpark. IA-10, S-1, S-7, S-10, Sarthe Challenge, Laguna Seca and of course Nurburgring - and many more, really the difficulty has went up. Which for me is good, however for less skilled players golds will be unobtainable.
