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

Execution · Practiced Mastery
A twin-stick looter shooter blending Housemarque arcade reflexes with a loot-grind build layer.

Execution · Practiced Mastery
A gritty African shooter where systemic chaos roughens every firefight.
Alienation leans Execution (Practiced Mastery); Far Cry 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Twin-stick aim and dodge under heavy swarm pressure.
Far Cry 2
Gunplay with degrading, jamming weapons
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Alien hordes never adapt.
Far Cry 2
Mercenary AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Random loot cores and weapon rolls.
Far Cry 2
Malaria, jams, and fire spread inject chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alienation
Build and core-socketing choices scale the endgame.
Far Cry 2
Loadout and route planning across hostile terrain
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.
