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 · Practiced Mastery
An open-world arcade racer across Australia where car control and tuning carry every event.

Execution · Pure Mechanics
A top-down shooter testing aim and movement against relentless enemy hordes.
Forza Horizon 3 leans Execution (Practiced Mastery); Serious Sam's Bogus Detour leans Execution (Pure Mechanics).
Serious Sam's Bogus Detour leans a little harder on execution, though the gap is small.
Forza Horizon 3
Car control and racing lines at speed
Serious Sam's Bogus Detour
Top-down aiming and crowd-dodging are the lead
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 3
Drivatars mimic but don't truly adapt
Serious Sam's Bogus Detour
Enemy hordes follow scripted rushes, not adaptive
Serious Sam's Bogus Detour leans a little harder on variance, though the gap is small.
Forza Horizon 3
Minor traffic and event variation
Serious Sam's Bogus Detour
Spawn timing and drops add some chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Forza Horizon 3
Tuning, car choice, and route knowledge
Serious Sam's Bogus Detour
Weapon choice and arena positioning matter underneath
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.
