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

Optimization · Pure Optimization
Methodical dungeon mapping and puzzle-solving with token real-time combat.

Optimization · Pure Optimization
A perk-driven sci-fi RPG won by flaw selection and dialogue routing.
Stonekeep leans Optimization (Pure Optimization); The Outer Worlds 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.
Stonekeep
Real-time mouse swings need only basic timing
The Outer Worlds
FPS-lite with time-dilation aim
The Outer Worlds leans a little harder on reads, though the gap is small.
Stonekeep
Dungeon denizens follow fixed scripts
The Outer Worlds
Scripted enemies
Stonekeep leans a little harder on variance, though the gap is small.
Stonekeep
Unmapped corridors and secrets are scripted-but-unknown
The Outer Worlds
Loot rolls, dialogue check variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Stonekeep
Mapping, rune magic and inventory puzzles are the real test
The Outer Worlds
Perks, flaws, dialogue routing rewarded
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.
