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
Open-world action game where procedurally generated orc captains remember your encounters.

Optimization · Practiced Mastery
Episodic survival horror pairing scarce-resource tension with co-op character switching.
Middle-earth: Shadow of Mordor leans Optimization (Practiced Mastery); Resident Evil Revelations 2 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
Resident Evil Revelations 2
Aiming under pressure and dodge timing against enemies.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Middle-earth: Shadow of Mordor
Nemesis orcs remember you but remain mappable scripts
Resident Evil Revelations 2
Scripted enemies and co-op partner; no adaptive opposition.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Middle-earth: Shadow of Mordor
Procedural captains with hidden strengths and weaknesses
Resident Evil Revelations 2
First-run scares, unknown layouts, raid mode loot rolls.
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
Resident Evil Revelations 2
Resource routing, enemy spawn knowledge, episode mastery once mapped.
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.
