I think he wanted to change coilovers, add turbos etc rather than just tweaking the setup.
I don't get why people compare it to Driveclub, that was so unrealistic and arcadey. This is a simulator, not really a game. The joy comes from shaving half a second off your lap, not holding a sick drift.
It's not comparable to forza, GT5 etc, it has it's own genre. People think it's difficult and therefore not worth buying. Try jumping straight into a Ginetta in the wet and see how you get on.
