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

Execution · Pure Mechanics
A late-90s mercenary FPS infamous for its graphic locational damage system.
Mario & Sonic at the Olympic Games leans Execution (Pure Mechanics); Soldier of Fortune 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.
Mario & Sonic at the Olympic Games
Motion timing and mashing rhythm decide event results
Soldier of Fortune
Fast twitch aim against fragile enemies decides everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario & Sonic at the Olympic Games
Human rivals race in parallel; little interaction
Soldier of Fortune
Multiplayer duels add a little human prediction
Soldier of Fortune leans a little harder on variance, though the gap is small.
Mario & Sonic at the Olympic Games
Events are fixed; almost no randomness
Soldier of Fortune
Campaign layouts and spawns are fixed
Soldier of Fortune leans a little harder on optimization, though the gap is small.
Mario & Sonic at the Olympic Games
Learning each event's optimal technique caps quickly
Soldier of Fortune
Weapon choice and level routes are quickly learned
