Optimization · Pure Optimization
An action RPG that crowns you king and tests your treasury more than your sword.

Scripted enemies
Seasons after Fall
No enemies or opponents at all
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
Seasons after Fall
World is fixed, nothing random
Fable III leans a little harder on optimization, though the gap is small.
Fable III
Treasury management and kingdom promises drive the endgame
