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

Optimization · Pure Optimization
Hardest modern-era Fire Emblem, a sprawling multi-army tactics campaign where planning around hit RNG is everything.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Fire Emblem: Radiant Dawn leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Fire Emblem: Radiant Dawn
Grid menus; no physical skill.
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.
Fire Emblem: Radiant Dawn
Enemy AI follows exploitable fixed priorities.
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Fire Emblem: Radiant Dawn leans clearly harder on variance.
Fire Emblem: Radiant Dawn
Hit, crit, and level-up rolls threaten permadeath plans.
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Fire Emblem: Radiant Dawn leans clearly harder on optimization.
Fire Emblem: Radiant Dawn
Unit deployment, BEXP routing, and map solutions dominate.
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.
