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
Linear military FPS about resisting an occupation of the United States.

Execution · Competitive PvP
An arcade soccer novelty testing timing around special-shot chaos.
Homefront leans Execution (Pure Mechanics); Mega Man Soccer leans Execution (Competitive PvP).
Homefront leans a little harder on execution, though the gap is small.
Homefront
Standard shooter gunplay carries the campaign
Mega Man Soccer
Sluggish controls still reward shot timing and positioning
Mega Man Soccer leans a little harder on reads, though the gap is small.
Homefront
Multiplayer adds some human prediction
Mega Man Soccer
Human opponents add light positional guessing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Homefront
Scripted setpieces, little randomness
Mega Man Soccer
Special-shot chaos adds some randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Homefront
Modest loadout and map knowledge layer
Mega Man Soccer
Team composition and special-shot management are shallow systems
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.
