head to head
NHL 2K6 asks more than The Witcher 3: Wild Hunt, and the gap is reads.

NHL 2K6
Human opponents disguise plays and bait pulls online
The Witcher 3: Wild Hunt

NHL 2K6
Rebounds and deflections add per-game noise
The Witcher 3: Wild Hunt
Loot rolls and minor combat variance only.
The Witcher 3: Wild Hunt leans a little harder on optimization, though the gap is small.
NHL 2K6
Line management and franchise decisions reward planning
The Witcher 3: Wild Hunt
Builds, alchemy, and quest routing reward planning.
