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

Optimization · Practiced Mastery
Wordless environmental puzzle decoding in a hostile world, with minimal combat demands.

Optimization · Pure Optimization
A grand strategy game set in a fictional matriarchal world.
Scorn leans Optimization (Practiced Mastery); Terra Feminarum 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.
Scorn
Clunky combat exists but avoidance usually suffices
Terra Feminarum
light strategic-map movement control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Scorn
Creatures wander on simple scripts, never adapting
Terra Feminarum
AI factions follow fixed strategic logic
Terra Feminarum leans a little harder on variance, though the gap is small.
Scorn
Opaque machinery puzzles are hidden logic until decoded
Terra Feminarum
battle outcomes and events randomized
Terra Feminarum leans a little harder on optimization, though the gap is small.
Scorn
Deciphering each biomechanical puzzle has one fixed solution
Terra Feminarum
empire management and strategy dominate play
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.
