head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
A stealth-action adventure where Aveline swaps social personas to move through 18th-century New Orleans.

Optimization · Pure Optimization
Villainous dungeon management game about luring monsters and crushing do-gooder heroes.
Assassin's Creed III: Liberation leans Optimization (Practiced Mastery); Dungeon Keeper 2 leans Optimization (Pure Optimization).
Assassin's Creed III: Liberation leans a little harder on execution, though the gap is small.
Assassin's Creed III: Liberation
Lenient parkour and counter combat set a low ceiling
Dungeon Keeper 2
Slap-and-drop micro and possession combat need quick hands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Guards follow patrol scripts without adapting
Dungeon Keeper 2
Hero waves and rival keepers run on scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed III: Liberation
Light patrol and notoriety randomness
Dungeon Keeper 2
Hero party timing and creature moods vary mildly.
Dungeon Keeper 2 leans a little harder on optimization, though the gap is small.
Assassin's Creed III: Liberation
Persona disguise system and mission routing reward planning
Dungeon Keeper 2
Dungeon layout, creature economy and research are solvable.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
