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
Mall zombie sandbox where a strict 72-hour schedule turns survival into a routing puzzle.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Dead Rising 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.
Dead Rising
Crowd-clearing melee and psychopath dodging are modestly demanding
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Dead Rising
Zombies and psychopaths follow fixed scripts
Fallout: New Vegas
Scripted factions and enemies
Dead Rising leans a little harder on variance, though the gap is small.
Dead Rising
Survivor AI pathing and zombie crowds add run noise
Fallout: New Vegas
Some loot and crit RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Rising
72-hour clock makes routing, scheduling, and PP farming the game
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
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.
