head to head
Destiny 2 asks more than Old School RuneScape, and the gap is execution.

Optimization · Practiced Mastery
A looter shooter where build optimization gates raid and seasonal content.

Optimization · Pure Optimization
An MMO solved through efficiency routing with niche tick-execution skill ceilings.
Destiny 2 leans Optimization (Practiced Mastery); Old School RuneScape leans Optimization (Pure Optimization).
Destiny 2 leans clearly harder on execution.
Destiny 2
Gunplay matters but raids forgive mechanics.
Old School RuneScape
Tick-perfect inputs in high-end PvM
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Destiny 2
PvE is scripted; Crucible has light adaptation.
Old School RuneScape
PvP wilderness has genuine read element
Destiny 2 leans a little harder on variance, though the gap is small.
Destiny 2
Loot drops and rolls drive the chase.
Old School RuneScape
Drop rates and clue RNG drive economy
Old School RuneScape leans a little harder on optimization, though the gap is small.
Destiny 2
Build crafting, mods, and damage rotations dominate.
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.
