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
Expanded machine combat with broader build systems and traversal tools.

Optimization · Practiced Mastery
Bethesda space RPG with ship and outpost systems.
Horizon Forbidden West 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.
Horizon Forbidden West
Faster combat with valor surges and aiming.
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.
Horizon Forbidden West
Machines remain scripted, not adaptive.
Starfield
Scripted NPC AI patterns
Starfield leans a little harder on variance, though the gap is small.
Horizon Forbidden West
Loot rolls and patrol RNG light.
Starfield
Procedural planets, loot variance
Starfield leans a little harder on optimization, though the gap is small.
Horizon Forbidden West
Deeper gear, weapon techniques, machine weaknesses.
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.
