I love the entire Forza series, whether we're talking about Motorsport or Horizon. Unfortunately, this particular one failed in my opinion. We were discussing a From The Ground Up game, but we're talking about a much inferior experience compared to the others and compared to any simcade title. *I play the game with a steering wheel.

POSITIVES:
+500+ cars.

NEGATIVES:
-Lacks modes like Drift, Drag, Split Screen, Free Roam
-Bad, boring, pointless Career.
-Bad A.I
-The handling of the cars feels like they have no grip.
-Bad sound design.
-Bad graphics both on PC and Console, with many cars having outdated models from previous Forza titles.
-Tracks that were present in previous games in the series have been removed.

Nice gameplay with plenty of driving customization options (from arcade to simulator). Better than the horizon.

Very good game, being a veteran of Forza Motorsport from 2 on the 360, I can say that the guys did a very good job... just don't expect the revolutionary game that will dethrone Gran Turismo...
single player: 7/10
graphics: 8/10
sound: 9/10
gameplay: 9/10
multiplayer: 9/10
longevity: 9/10
overall: 8.5/10
edit: after an update, the game freezes, some disconnections in multiplayer, the new cars are all paid, something unacceptable even for Microsoft's standards. Final rating from me: 3/5

Lower than expected, very disappointed with the game.... the cars do not have good driving behavior.. you have to play with each car for a long time to unlock the upgrades.... the game needs many updates and the graphics could have been better for next gen as well...
