Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fable III
Scripted enemies
The Witcher

The Witcher leans a little harder on variance, though the gap is small.
Fable III
Largely fixed world
The Witcher

The Witcher leans a little harder on optimization, though the gap is small.

Treasury management and kingdom promises drive the endgame
The Witcher
