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

Optimization · Pure Optimization
A tower-defense hybrid about summoning units and upgrading to survive waves.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Bardbarian leans Optimization (Pure Optimization); Fallout: New Vegas 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.
Bardbarian
Movement dodging matters but isn't the lead
Fallout: New Vegas
Shooter inputs with VATS assist
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bardbarian
Enemy waves are scripted, not adaptive
Fallout: New Vegas
Scripted factions and enemies
Bardbarian leans a little harder on variance, though the gap is small.
Bardbarian
Wave composition and drops vary somewhat
Fallout: New Vegas
Some loot and crit RNG
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Bardbarian
Summoning units and upgrade choices win waves
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
