head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
The faithful remaster of Diablo II preserving its loot grind and build depth under new graphics.

Optimization · Pure Optimization
An auto-battling deckbuilder about building a loop to defeat the Lich.
Diablo II: Resurrected leans Optimization (Pure Optimization); Loop Hero leans Optimization (Pure Optimization).
Diablo II: Resurrected leans a little harder on execution, though the gap is small.
Diablo II: Resurrected
Same forgiving click combat as the original
Loop Hero
Autobattler, almost no inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo II: Resurrected
Identical scripted monster AI
Loop Hero
Enemies follow scripts.
Diablo II: Resurrected leans a little harder on variance, though the gap is small.
Diablo II: Resurrected
Loot tables and area randomization rule drops
Loop Hero
Card draws and loot drops randomize.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Diablo II: Resurrected
Decades of solved builds, breakpoints, and farming routes
Loop Hero
Deck and tile placement reward deep optimization.
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.
