head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Optimization · Pure Optimization
The expanded sequel sending the SMERSH operative on more elaborate WWII infiltration missions.
Dead Rising leans Optimization (Pure Optimization); Death to Spies: Moment of Truth 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
Death to Spies: Moment of Truth
Stealth inputs are forgiving once the plan exists
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Rising
Zombies and psychopaths follow fixed scripts
Death to Spies: Moment of Truth
Guards never learn from your previous attempts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Rising
Survivor AI pathing and zombie crowds add run noise
Death to Spies: Moment of Truth
Initial uncertainty about patrols and objective placement
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
Death to Spies: Moment of Truth
Perfect routes through clockwork levels are fully solvable
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.
