Also, I find the full price for an "update" an exaggeration, because the image has not really changed. Although the new Grand Prix (Sochi, Spielberg) and also the change from the Nürburgring to the Hockenheimring were well integrated into the game, but this is not enough in my opinion made to justify the price.
I hope that the 2015er version finally included a new graphics engine, and perhaps a new damage model, otherwise this version is left on the left.
