Back in the good old Atari 2600 days, replicating a car in a computer game was a simple matter. A vaguely vehicle-shaped blob formed of a few dozen blocky pixels, and a buzzy ‘engine note' soundtrack that rose and fell with no relation to your speed? Good enough for us, ta.
But today, gamers want rather more. Demand it, in fact.
You want to feel the car reacting to your inputs, as it would in real life. To see it fall to bits when you sadistically smash it up. And to have the latest models available to download as soon as the sheets are pulled off them at a motor show.
