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 deep dual-class build system where optimising passive constellations and resist thresholds is the core challenge.
Dead Rising leans Optimization (Pure Optimization); Grim Dawn 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
Grim Dawn
Boss fights and Crucible have limited twitch demand
Grim Dawn leans a little harder on reads, though the gap is small.
Dead Rising
Zombies and psychopaths follow fixed scripts
Grim Dawn
Solo and co-op PvE throughout; no adaptive opponent
Grim Dawn leans a little harder on variance, though the gap is small.
Dead Rising
Survivor AI pathing and zombie crowds add run noise
Grim Dawn
Drop RNG and component rolls add moderate hidden information
Grim Dawn leans a little harder on optimization, though the gap is small.
Dead Rising
72-hour clock makes routing, scheduling, and PP farming the game
Grim Dawn
Dual-class mastery system and devotion tree are extensively 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.
