Here is my opinion of the demo. I think the graphics level is a little better than the previous one, the colors also look better to me. I think the sound of the co-pilot is also a little better. I like the dashcam closer and without the black glass strip on top. The cockpits are no longer dark either.
In terms of physics, these seams quite strange to me. The car seems that it doesn't have as much weight/aerodynamic load as the previous one (WRC 9). The car at low speeds on gravel slides a lot. It has to have more grip. On tarmac something is off also.
Car sounds are a disgrace, especially when you lift your foot off the throtle. In the replays then...
.
Update: its seams better in a more advanced version of this game...
I'm not very confident about this game, but we'll see it until its release.
I would like to hear your feedback too.
