head to head
Neither is simply harder - they are hard in different places. Fallout: New Vegas demands more execution; Stranger of Sword City demands more variance.

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

Optimization · Pure Optimization
Party-build optimisation and risk management in a punishing turn-based dungeon crawl.
Fallout: New Vegas leans Optimization (Pure Optimization); Stranger of Sword City leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Stranger of Sword City
Turn-based menus carry no physical demand
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Stranger of Sword City
Monsters follow fixed logic with no adaptation
Stranger of Sword City leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Stranger of Sword City
Encounter rolls, drops and permadeath risk shape runs
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
Stranger of Sword City
Party builds, class changes and risk management are the game
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.
