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

Optimization · Pure Optimization
A grid-based dungeon crawler about deep party building and environmental puzzles.

Optimization · Pure Optimization
Classic open-world RPG where stats and broken crafting systems trump twitch skill.
The Bard's Tale IV leans Optimization (Pure Optimization); The Elder Scrolls III: Morrowind leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
The Bard's Tale IV
grid-based combat needs little manual skill
The Elder Scrolls III: Morrowind
Dice-roll combat ignores aim skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Bard's Tale IV
scripted monster AI, no true adaptation
The Elder Scrolls III: Morrowind
No adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Bard's Tale IV
loot and encounter randomness
The Elder Scrolls III: Morrowind
Hit chances rolled behind the screen
The Bard's Tale IV leans a little harder on optimization, though the gap is small.
The Bard's Tale IV
deep party build and puzzle-solving systems
The Elder Scrolls III: Morrowind
Alchemy and spellcrafting are famously 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.
