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

Villainous dungeon management game about luring monsters and crushing do-gooder heroes.

Optimization · Pure Optimization
Narrative stealth puzzles solved by planning routes through scripted patrols.
Dungeon Keeper 2 leans Optimization (Pure Optimization); Eriksholm: The Stolen Dream leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Keeper 2
Slap-and-drop micro and possession combat need quick hands.
Eriksholm: The Stolen Dream
Timing patrol gaps needs only modest dexterity
Dungeon Keeper 2 leans a little harder on reads, though the gap is small.
Dungeon Keeper 2
Hero waves and rival keepers run on scripts.
Eriksholm: The Stolen Dream
Guards run fixed vision cones and routes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Keeper 2
Hero party timing and creature moods vary mildly.
Eriksholm: The Stolen Dream
Each scene is fully readable before acting
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Keeper 2
Dungeon layout, creature economy and research are solvable.
Eriksholm: The Stolen Dream
Solving multi-character stealth routes is the whole game
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.
