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 · Pure Optimization
A deep dual-class build system where optimising passive constellations and resist thresholds is the core challenge.

Optimization · Pure Optimization
The classic survival horror sequel where ammo budgeting and route knowledge tame Raccoon City.
Grim Dawn leans Optimization (Pure Optimization); Resident Evil 2 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Grim Dawn
Boss fights and Crucible have limited twitch demand
Resident Evil 2
Tank controls and aim need competence, not mastery
Grim Dawn leans a little harder on reads, though the gap is small.
Grim Dawn
Solo and co-op PvE throughout; no adaptive opponent
Resident Evil 2
Zombies are scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grim Dawn
Drop RNG and component rolls add moderate hidden information
Resident Evil 2
First-run item and enemy placement is hidden information
Grim Dawn leans a little harder on optimization, though the gap is small.
Grim Dawn
Dual-class mastery system and devotion tree are extensively solvable
Resident Evil 2
Routing, ammo economy, and puzzles fully converge on replay
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.
