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
An action-RPG hybrid driven by crafting, specialization, and war-table routing.

Optimization · Pure Optimization
A stealth sim about casing houses and planning optimal heists.
Dragon Age: Inquisition leans Optimization (Pure Optimization); Thief Simulator 2 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.
Dragon Age: Inquisition
Action-leaning combat, dodge timing matters
Thief Simulator 2
Lockpicking and stealth timing matter but stay light
Thief Simulator 2 leans a little harder on reads, though the gap is small.
Dragon Age: Inquisition
Scripted enemy behaviour
Thief Simulator 2
NPC patrols follow scripted routes, not adaptive
Thief Simulator 2 leans a little harder on variance, though the gap is small.
Dragon Age: Inquisition
Some loot randomization
Thief Simulator 2
Loot contents and patrol timing add mild uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Inquisition
Crafting, specialization, war table planning
Thief Simulator 2
Planning routes, tools and casing targets is the core
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.
