Fable III leans a little harder on execution, though the gap is small.
Fable III

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
PC Building Simulator
No opponent; clients issue fixed job tickets.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fable III
Largely fixed world
PC Building Simulator
Job orders vary slightly day to day.
PC Building Simulator leans a little harder on optimization, though the gap is small.
