Why do I NOT recommend this game?
First of all: Games for Windows. Steam should put a big banner on all products where you require any DRM service other than Steam so you don't have to look for it inbetween the lines or be suprised after purchase. This GfW dependancy might be sorted out in the near future, so perhaps then you might give it a try.
The second reason? The console-style menus are - as always - rubbish. To get from the race of one cup or championship to another you have to click through several inception style layers of menus and each transition is followed by annoying animations that prolong the whole process. Doing this on a PC is really unnecessary.
Third reason: The number of cheesy comments is simply over-the-top. After and before each race I am constantly reminded how awesome I am, how mind-blowing progress I am making and how my fans all love me like 1970 rockstar groupies. Oh, and that I should post every race on YouTube. What is the point of that? I am not a twelve-year-old.
The fourth reason may be too little rally and too much gymkhana, but most people are already used to that in the Dirt series.
The racing itself is pretty solid, and it would be an overall good game if not for the annoying reasons I stated above.
