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

Optimization · Pure Optimization
Optimising a dwarf fortress economy against a randomly generated world.

Optimization · Pure Optimization
Classic open-world RPG where stats and broken crafting systems trump twitch skill.

The Elder Scrolls III: Morrowind

Random world generation hides resources until dug out
The Elder Scrolls III: Morrowind
