head to head
Ori and the Will of the Wisps asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
A more combat-forward sequel with sharper platforming demands.
Half-Life 2 leans Execution (Pure Mechanics); Ori and the Will of the Wisps leans Execution (Pure Mechanics).
Ori and the Will of the Wisps leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
Ori and the Will of the Wisps
Combat plus escape chases demand tight inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Combine AI scripted, non-adaptive.
Ori and the Will of the Wisps
Scripted bosses, no human opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
Ori and the Will of the Wisps
Deterministic encounters
Ori and the Will of the Wisps leans clearly harder on optimization.
Half-Life 2
Linear progression with no builds.
Ori and the Will of the Wisps
Shard loadouts and weapon choice tune playstyle
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.
