Arma 3vsMarathon
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.
Arma 3
Execution · Grand Arena
Open military simulator and PvP sandbox.
Marathon
Execution · Competitive PvP
Aim duels against human crews layered over hidden-information loot gambles and extraction timing.
Arma 3 leans Execution (Grand Arena); Marathon leans Execution (Competitive PvP).
Arma 3Marathon
Axis by axis
Execution8 vs 8
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Arma 3
Bullet drop, stance, sway, weight all matter
Marathon
Gunfights against other crews reward raw aim heavily
Reads7 vs 7
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arma 3
PvP and milsim ops reward prediction
Marathon
Predicting human crews' rotations and ambushes is constant
Variance4 vs 5
Marathon leans a little harder on variance, though the gap is small.
Arma 3
Mission scripts and AI behavior vary
Marathon
Loot spawns and unseen squads create hidden information
Optimization6 vs 5
Arma 3 leans a little harder on optimization, though the gap is small.
Arma 3
Loadout planning and tactics solvable
Marathon
Loadout economics and extraction routing sit underneath
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.
