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

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Routing a fragile goblin through dense layered patrols using precise tool and ability economics.
Fallout: New Vegas leans Optimization (Pure Optimization); Styx: Master of Shadows 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.
Fallout: New Vegas
Shooter inputs with VATS assist
Styx: Master of Shadows
Ledge-grab timing and kill animations need decent precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Scripted factions and enemies
Styx: Master of Shadows
Orcs march fixed patrols; no adaptive opponent awareness
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Some loot and crit RNG
Styx: Master of Shadows
Checkpoint placements and gold locations are consistent per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Styx: Master of Shadows
Rope routing, amber-clone use, and distraction sequencing are optimisable
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.
