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
An upgrade-economy loop where spending order matters more than driving.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Earn to Die 2 leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim 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.
Earn to Die 2
Throttle and tilt control matter mildly per run
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Earn to Die 2
Zombies are static obstacles, not minds
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Earn to Die 2
Obstacle layouts vary lightly between runs
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Upgrade purchase order is the real progression engine
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
