head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
A lo-fi survival horror game where strict inventory limits and puzzle knowledge define the mastery curve.

Optimization · Practiced Mastery
Bethesda space RPG with ship and outpost systems.
Signalis leans Optimization (Practiced Mastery); Starfield leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Signalis
Careful aim and kiting in limited inventory combat matter
Starfield
Shooter and piloting inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Signalis
Replika AI follows aggressive scripted loops, not player modelling
Starfield
Scripted NPC AI patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Signalis
Enemy respawn timing and some item locations add limited uncertainty
Starfield
Procedural planets, loot variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Signalis
Inventory management, puzzle solutions and route planning are central
Starfield
Ship building, outpost, perk routing
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.
