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.

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

Optimization · Pure Optimization
A tower-defense game with whimsical creature waves.
Dungeon Keeper 2 leans Optimization (Pure Optimization); Krinkle Krusher 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.
Krinkle Krusher
light real-time placement timing
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.
Krinkle Krusher
no adaptive opponent, waves are scripted
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.
Krinkle Krusher
random enemy wave composition
Dungeon Keeper 2 leans a little harder on optimization, though the gap is small.
Dungeon Keeper 2
Dungeon layout, creature economy and research are solvable.
Krinkle Krusher
tower and unit placement strategy
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.
