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

Optimization · Practiced Mastery
A tap-to-shoot defense game balancing aim with weapon upgrade choices.

Optimization · Practiced Mastery
Recruit-anyone London where operative variety carries every mission.
Swamp Attack leans Optimization (Practiced Mastery); Watch Dogs: Legion leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Swamp Attack
Tap-aiming at incoming enemies needs modest timing
Watch Dogs: Legion
Combat and driving forgiving across operatives.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Swamp Attack
Waves are scripted, no adaptive opponent
Watch Dogs: Legion
AI scripted; no real modeling.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Swamp Attack
Enemy spawn mix adds some randomness across waves
Watch Dogs: Legion
Recruit perks and patrols randomize widely.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Swamp Attack
Weapon and upgrade choices shape wave survival
Watch Dogs: Legion
Recruit synergy, gadgets, routes solvable.
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.
