Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
An MMO solved through efficiency routing with niche tick-execution skill ceilings.

Optimization · Pure Optimization
A space tower-defense game solved by optimal module placement under timed pressure.
Old School RuneScape leans Optimization (Pure Optimization); Space Run: Fast and Safe Delivery leans Optimization (Pure Optimization).
Old School RuneScape leans a little harder on execution, though the gap is small.
Old School RuneScape
Tick-perfect inputs in high-end PvM
Space Run: Fast and Safe Delivery

PvP wilderness has genuine read element
Space Run: Fast and Safe Delivery
Enemy waves are scripted, not adapting to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Old School RuneScape
Drop rates and clue RNG drive economy
Space Run: Fast and Safe Delivery
Wave compositions and timing add bounded surprises
Old School RuneScape leans a little harder on optimization, though the gap is small.

Efficiency, routing, and GP/hour fully theorycrafted
Space Run: Fast and Safe Delivery
Optimal weapon placement and resource use win runs
