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
Stealth routing that converges to memorised guard patterns and item paths.
Fallout: New Vegas leans Optimization (Pure Optimization); Snake's Revenge 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
Snake's Revenge
Dodging guards and boss fights need modest precision
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Snake's Revenge
Guard patrols are fixed scripts, not minds
Snake's Revenge leans a little harder on variance, though the gap is small.
Fallout: New Vegas
Some loot and crit RNG
Snake's Revenge
Layouts and patrols unknown on first pass only
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Snake's Revenge
Memorising routes and guard cycles is the core test
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.
