head to head
Neither is simply harder - they are hard in different places. Gloomhaven demands more variance; The Elder Scrolls V: Skyrim demands more execution.

Optimization · Pure Optimization
Sprawling tactical dungeon crawler where managing a dwindling hand of cards decides everything.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Gloomhaven leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Gloomhaven
Turn-based; zero dexterity demand
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
Gloomhaven leans a little harder on reads, though the gap is small.
Gloomhaven
Monster AI follows printed, mappable rules
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Gloomhaven leans clearly harder on variance.
Gloomhaven
Modifier deck and monster ability draws
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Gloomhaven leans clearly harder on optimization.
Gloomhaven
Card economy and scenario routing are the game
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
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.
