head to head
Grid 2 asks more than The Witcher 3: Wild Hunt, and the gap is execution.

Execution · Practiced Mastery
Cornering execution over memorisable circuits, with light prediction in wheel-to-wheel multiplayer.

Optimization · Practiced Mastery
A narrative action RPG where build planning matters more than reflex execution.
Grid 2 leans Execution (Practiced Mastery); The Witcher 3: Wild Hunt leans Optimization (Practiced Mastery).

Racing lines, braking points and car selection are studyable
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing reward planning.
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.
