As with all such things, the key to making a good rally game is wedged in the door marked 'pub'. "You sit late in bars with drivers and co-drivers talking about how these things work," says SEGA Racing Studio boss Guy Wilday. Then you go home and do some programming. Eurogamer ask so what do rally drivers say? "It's all about tyres, and it's all about surfaces. That really is a key topic of conversation. The cars themselves are obviously very technically innovative, but the thing they focus on is the tyres and the surfaces - what tyres they need for a particular surface, how a car is going to behave on a particular surface, and how that surface is going to change."
