PSLS: After getting some hands-on time with the game, I did notice that there was a very robust customization system behind the available car. Are you worried that such depth will be over the heads of the more casual racing fan?
AT: It is kind of a dark art, like tuning and things like that. We are actually using the community to help us there, because every game we have worked on has had tuning into it and we have tried to educate players on what things do to make them better at it. Initially we were going to have the actual help in the game, but nowadays with second screen apps and the community aspect of it, it is actually better to have it as a wiki. In the game there’s help, there’s text on the screen to inform you and tell you what to do, but if you go to our website, the community have created a frequently asked questions section.
So, if you ask why your car isn’t turning. It is as simple as that, and it will give you a description from a human being, not like a technical manual. If you go to our Youtube channel, we have a series of video’s called Race Control, and it is like humans, players, like yourselves playing the game and teaching you the game and how to drive, tuning aspects and things like that. So, we would rather your friends tell you what to do, than to have a game, or a technical manual tell you how to do it, and hopefully you will come into
Project CARS with more information than you actually came in with.
