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.

Optimization · Practiced Mastery
Open-world action game where procedurally generated orc captains remember your encounters.

Optimization · Practiced Mastery
A looter-shooter loop testing build optimisation more than the shooting itself.
Middle-earth: Shadow of Mordor 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.
Middle-earth: Shadow of Mordor
Counter-timing combat and stealth execution
Suicide Squad: Kill the Justice League
Traversal-shooting needs moderate aim, generous by shooter standards
Middle-earth: Shadow of Mordor leans a little harder on reads, though the gap is small.
Middle-earth: Shadow of Mordor
Nemesis orcs remember you but remain mappable scripts
Suicide Squad: Kill the Justice League
Brainwashed bosses are scripted encounters
Middle-earth: Shadow of Mordor leans a little harder on variance, though the gap is small.
Middle-earth: Shadow of Mordor
Procedural captains with hidden strengths and weaknesses
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.
Middle-earth: Shadow of Mordor
Intel gathering and exploiting known weaknesses solves fights
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.
