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

Optimization · Pure Optimization
An MMO solved through efficiency routing with niche tick-execution skill ceilings.
Deus Ex leans Optimization (Pure Optimization); Old School RuneScape 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
Old School RuneScape
Tick-perfect inputs in high-end PvM
Old School RuneScape leans a little harder on reads, though the gap is small.
Deus Ex
NPCs follow scripted patrol routes, not adaptive modelling
Old School RuneScape
PvP wilderness has genuine read element
Old School RuneScape leans a little harder on variance, though the gap is small.
Deus Ex
Enemy placements and item locations are fixed but initially hidden
Old School RuneScape
Drop rates and clue RNG drive economy
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
Old School RuneScape
Efficiency, routing, and GP/hour fully theorycrafted
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.
