head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Sequel continuing the Alma horror story with mech sequences and slow-motion combat.

Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.
F.E.A.R. 2: Project Origin leans Execution (Pure Mechanics); Mario Bros. leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Aim and slow-mo trigger discipline
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Enemy squads are clever but scripted
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Minor spawn and cover variation
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
F.E.A.R. 2: Project Origin
Learning arenas and ability usage
Mario Bros.
POW block usage and enemy routing have known best lines
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.
