I am not gonna write anything about historical content, because it is a really great content. But from the audiovisual and gameplay point of view, this is a disaster.
I don't have a rally car in my garage, but I've visited hundreds of WRC rally events in my life and unfortunately what the game offers in terms of sound is a mockery. This is definitely not how rally cars sound. There is nothing to comment here. It's better to turn off the sound.
Graphically, we are dealing with a huge regression. For a comparison, I ran an old WRC 7 and V-Rally 4, and rubbed my eyes with amazement. How can it be, to release such a bad looking game when the previous games are looking so good?! And I completely do not understand why the level of historical 3D cars models differs so much from the rest?! They have an awfully small amount of details and are poorly reproduced. For example Colin McRae's Subaru Impreza, it's actually some kind of Subaru. I already omit the poor quality textures and the notoriously appearing and disappearing elements of the environment during a rallying. This is very easy to see while watching replays.
And finally, the best... physics or driving model. The cars does drive... that's good. And that's it. With the assists turned off, the game does not require any major skills from the player at all. Or maybe I am so good...
It is very easy. Too easy... With assists turned on? This is a game for "children".
But to be honest... It's still a very enjoyable game. Such a Need for Speed Porsche...
It supposedly simulates real car behavior on the road, but it also allows for uncompromising hands-off driving.
