head to head
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
A pausable tactics RPG where party build and tactic-slot planning win fights.

Optimization · Pure Optimization
A blade-driven JRPG won by chain-attack routing and combo optimization.
Dragon Age: Origins leans Optimization (Pure Optimization); Xenoblade Chronicles 2 leans Optimization (Pure Optimization).
Xenoblade Chronicles 2 leans a little harder on execution, though the gap is small.
Dragon Age: Origins
Tactical pause combat, low input demand
Xenoblade Chronicles 2
Auto-attack with art-timing inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Enemy AI is scripted
Xenoblade Chronicles 2
Scripted enemies
Xenoblade Chronicles 2 leans a little harder on variance, though the gap is small.
Dragon Age: Origins
Hidden rolls and loot tables
Xenoblade Chronicles 2
Blade gacha and crit rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Tactics slots, builds, party synergy dominate
Xenoblade Chronicles 2
Blade combos and chain attack routing central
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.
