Execution · Practiced Mastery
Loose action execution and horde-building through scripted comedy set-pieces.

Optimization · Practiced Mastery

Limb-throwing and horde wrangling need only loose aim
The Witcher 3: Wild Hunt

Stubbs the Zombie in Rebel Without a Pulse
Townsfolk and soldiers follow scripted AI
The Witcher 3: Wild Hunt

The Witcher 3: Wild Hunt leans a little harder on variance, though the gap is small.
Stubbs the Zombie in Rebel Without a Pulse

The Witcher 3: Wild Hunt

Conversion economy - building your horde - rewards light planning
The Witcher 3: Wild Hunt
