head to head
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 systemic immersive sim where augmentation choices and route planning determine how every obstacle falls.

Optimization · Pure Optimization
A deep dual-class build system where optimising passive constellations and resist thresholds is the core challenge.
Deus Ex 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.
Deus Ex
Aiming and movement matter but never define victory
Grim Dawn
Boss fights and Crucible have limited twitch demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex
NPCs follow scripted patrol routes, not adaptive modelling
Grim Dawn
Solo and co-op PvE throughout; no adaptive opponent
Grim Dawn leans a little harder on variance, though the gap is small.
Deus Ex
Enemy placements and item locations are fixed but initially hidden
Grim Dawn
Drop RNG and component rolls add moderate hidden information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deus Ex
Augmentation builds, routes, and tool choices are the core system
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.
