head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

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

Optimization · Pure Optimization
Survival horror testing inventory routing and ammo economy through a fixed mansion of scripts.
Fallout: New Vegas leans Optimization (Pure Optimization); Resident Evil Code: Veronica X 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
Resident Evil Code: Veronica X
Tank controls and aimed shots under pressure need composure
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Resident Evil Code: Veronica X
Zombies and bosses follow fixed scripted behaviour
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
Resident Evil Code: Veronica X
Item placements are scripted-but-unknown on first runs
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Resident Evil Code: Veronica X
Ammo economy, item routing and key puzzles drive everything
