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

Optimization · Pure Optimization
Optimising RPG skill builds and tower placement against scripted enemy waves.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Defender's Quest: Valley of the Forgotten leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim leans Optimization (Pure Optimization).
The Elder Scrolls V: Skyrim leans a little harder on execution, though the gap is small.
Defender's Quest: Valley of the Forgotten
Mid-wave placement clicks barely tax the hands
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.
Defender's Quest: Valley of the Forgotten
Enemy waves march on fixed paths without adapting
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.
Defender's Quest: Valley of the Forgotten
Wave compositions surprise only on first attempts
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Defender's Quest: Valley of the Forgotten leans a little harder on optimization, though the gap is small.
Defender's Quest: Valley of the Forgotten
Skill trees, gear and placement math are the entire test
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.
