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

Execution · Practiced Mastery
A nanosuit-powered FPS where you choose between cloaked stealth and armored assault through a ruined New York.

Execution · Pure Mechanics
A late-90s mercenary FPS infamous for its graphic locational damage system.
Crysis 2 leans Execution (Practiced Mastery); 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.
Crysis 2
Aimbot trivialises every firefight; aim and movement carry it
Soldier of Fortune
Fast twitch aim against fragile enemies decides everything
Soldier of Fortune leans a little harder on reads, though the gap is small.
Crysis 2
Scripted Ceph and soldiers follow fixed patterns
Soldier of Fortune
Multiplayer duels add a little human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crysis 2
Mostly known encounters with mild patrol randomness
Soldier of Fortune
Campaign layouts and spawns are fixed
Crysis 2 leans a little harder on optimization, though the gap is small.
Crysis 2
Suit energy management and choosing stealth-versus-armor approaches
Soldier of Fortune
Weapon choice and level routes are quickly learned
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.
