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
Managing scarce resources and learning authored scares that converge to routed runs.

Optimization · Practiced Mastery
A looter-shooter loop testing build optimisation more than the shooting itself.
Resident Evil Requiem leans Optimization (Practiced Mastery); Suicide Squad: Kill the Justice League 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.
Resident Evil Requiem
Aiming under pressure matters but stays survivable
Suicide Squad: Kill the Justice League
Traversal-shooting needs moderate aim, generous by shooter standards
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil Requiem
Enemies and stalkers follow designed behaviour, not adaptive minds
Suicide Squad: Kill the Justice League
Brainwashed bosses are scripted encounters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil Requiem
First-run horror trades on scripted-but-unknown encounters
Suicide Squad: Kill the Justice League
Loot rolls gate the live-service grind
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil Requiem
Resource management and routing converge on optimal runs
Suicide Squad: Kill the Justice League
Gear builds and mission farming dominate endgame
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.
