Forza Horizon 2: 82
DriveClub: 72
Project CARS: 80

Takes easily the price for "worst post in thread". Sorry but these type of posts are absolutely nonsense.

So many followed my guess that Horizon 2 will score better than DC. Perhaps after E3 footage we will finally make more educated guesses.

New Forza Horizon 2 footage from E3!

 

I'll predict the following scores:
Forza Horizon 2: 88
Driveclub: 80
Project Cars: 83

After seeing the footage from Forza Horizon 2 I am quite sure the game will be a worthy successor of the first Horizon which was fun as fu**. So I hope it will get high ratings, definitely above 85.
DC looks also fun currently but I am more pleased by the graphics currently than what they are delivering with gameplay.

So after new info is out for every game:
Did you change your opinion? For me it still looks like Forza Horizon 2 will win the meta-score by at least 5 points.
Especially after reading this: http://www.eurogamer.net/articles/2014-08-19-forza-horizon-2-proves-the-driving-genre-is-back-at-its-best

Forza Horizon 2: 79

Driveclub: 79

Project CARS: 75

You expect DC and FH2 the same? Wow, that's a bold prediction ;)
