head to head
Risk of Rain 2 asks more than Deus Ex, and the gap is variance.

Optimization · Pure Optimization
A systemic immersive sim where augmentation choices and route planning determine how every obstacle falls.

Optimization · Pure Optimization
A third-person roguelike where item snowballs outscale the difficulty timer.
Deus Ex leans Optimization (Pure Optimization); Risk of Rain 2 leans Optimization (Pure Optimization).
Risk of Rain 2 leans a little harder on execution, though the gap is small.
Deus Ex
Aiming and movement matter but never define victory
Risk of Rain 2
Aim and movement matter under escalating swarm pressure.
Deus Ex leans a little harder on reads, though the gap is small.
Deus Ex
NPCs follow scripted patrol routes, not adaptive modelling
Risk of Rain 2
Enemies follow fixed AI; no opponent models you.
Risk of Rain 2 leans clearly harder on variance.
Deus Ex
Enemy placements and item locations are fixed but initially hidden
Risk of Rain 2
Item drops and stage selection randomized each run.
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
Risk of Rain 2
Item stacking and scaling routes dominate run outcomes.
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.
