head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
Open-world racing testing car control and line discipline with light tuning underneath.

Execution · Pure Mechanics
Absurd physics limb control tested under a timer atop a tower of friends.
Forza Horizon 2 leans Execution (Pure Mechanics); Mount Your Friends leans Execution (Pure Mechanics).
Mount Your Friends leans a little harder on execution, though the gap is small.
Forza Horizon 2
Racing lines, braking points and car control lead everything
Mount Your Friends
QWOP-like limb control under a timer is the entire challenge
Mount Your Friends leans a little harder on reads, though the gap is small.
Forza Horizon 2
Drivatar AI mimics styles but stays effectively scripted
Mount Your Friends
Rivals shape the tower but climbing is solo execution
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 2
Weather shifts grip slightly; courses are fully known
Mount Your Friends
The stack you face is visible, nothing hidden
Forza Horizon 2 leans a little harder on optimization, though the gap is small.
Forza Horizon 2
Car tuning and route knowledge reward preparation
Mount Your Friends
Grip-route planning up the pile helps marginally
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
