head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
PS2 RPG pairing randomized dungeon crawls with rebuilding ruined towns.

Optimization · Pure Optimization
A dwarven survival-crafting expedition where managing ore, gear and bases outweighs swordplay.
Dark Cloud leans Optimization (Pure Optimization); The Lord of the Rings: Return to Moria 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.
Dark Cloud
real-time dungeon combat with weapon timing
The Lord of the Rings: Return to Moria
Stamina-based melee needs modest timing and positioning.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud
no adaptive opponent
The Lord of the Rings: Return to Moria
Orc hordes are scripted spawns, not adaptive minds.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud
randomized dungeon floors and drops
The Lord of the Rings: Return to Moria
Procedurally generated mines hide ore, dangers and routes.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud
weapon evolution and town-building reward planning
The Lord of the Rings: Return to Moria
Base building, gear tiers and resource chains decide survival.
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.
