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 · Pure Optimization
A party-based loot ARPG marching a customizable squad across Aranna against Valdis.

Optimization · Pure Optimization
An auto-battling deckbuilder about building a loop to defeat the Lich.
Dungeon Siege II leans Optimization (Pure Optimization); Loop Hero leans Optimization (Pure Optimization).
Dungeon Siege II leans a little harder on execution, though the gap is small.
Dungeon Siege II
Party combat mostly automates itself
Loop Hero
Autobattler, almost no inputs.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Siege II
Enemies follow simple scripts
Loop Hero
Enemies follow scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Siege II
Random loot and chant rewards
Loop Hero
Card draws and loot drops randomize.
Loop Hero leans a little harder on optimization, though the gap is small.
Dungeon Siege II
Party composition, pet raising, skill tree planning
Loop Hero
Deck and tile placement reward deep optimization.
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.
