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
Planning guerilla engagements against patrolling machines with component weak points.

Optimization · Practiced Mastery
Bethesda space RPG with ship and outpost systems.
Generation Zero 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.
Generation Zero
Aiming at weak points and repositioning needs steady hands
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.
Generation Zero
Machines follow sensor-driven routines, not adaptive modelling
Starfield
Scripted NPC AI patterns
Generation Zero leans a little harder on variance, though the gap is small.
Generation Zero
Patrol positions and loot are unknown until scouted
Starfield
Procedural planets, loot variance
Starfield leans a little harder on optimization, though the gap is small.
Generation Zero
Loadout building and guerilla engagement planning carry fights
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.
