head to head
Neither is simply harder - they are hard in different places. Blackguards 2 demands more variance; The Elder Scrolls V: Skyrim demands more execution.

Optimization · Pure Optimization
Deep hex-battle build optimization with dice variance layered over every action.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Blackguards 2 leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans clearly harder on execution.
Blackguards 2
Hex-grid turns carry no physical demand
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.
Blackguards 2
Enemy AI follows fixed tactical logic
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Blackguards 2 leans clearly harder on variance.
Blackguards 2
Dark Eye dice rolls swing individual actions
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Blackguards 2 leans a little harder on optimization, though the gap is small.
Blackguards 2
Build planning and battlefield manipulation are the deep solvable core
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.
