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 · Practiced Mastery
Bethesda space RPG with ship and outpost systems.

Optimization · Pure Optimization
A hybrid real-time and tactical action RPG in a digital city.
Starfield leans Optimization (Practiced Mastery); Transistor leans Optimization (Pure Optimization).
Starfield leans a little harder on execution, though the gap is small.
Starfield
Shooter and piloting inputs
Transistor
Real-time and planned hybrid combat.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Starfield
Scripted NPC AI patterns
Transistor
Process enemies follow scripts.
Starfield leans a little harder on variance, though the gap is small.
Starfield
Procedural planets, loot variance
Transistor
Limited randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Starfield
Ship building, outpost, perk routing
Transistor
Function loadouts have deep optimization.
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.
