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

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

Optimization · Systems & Chaos
A charming casual dungeon crawler of endless randomized levels, fishing, and a loyal pet.
Dungeon Siege II leans Optimization (Pure Optimization); Fate leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Dungeon Siege II
Party combat mostly automates itself
Fate
Simple click combat with a pet tank
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
Fate
Dungeon monsters fully scripted
Fate leans a little harder on variance, though the gap is small.
Dungeon Siege II
Random loot and chant rewards
Fate
Random dungeon levels, loot, and fishing rewards
Dungeon Siege II leans a little harder on optimization, though the gap is small.
Dungeon Siege II
Party composition, pet raising, skill tree planning
Fate
Pet feeding, gem socketing, fame quest efficiency
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.
