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

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
As Dusk Falls
Timed vote prompts create mild urgency but no skill ceiling
Dungeon Siege

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
As Dusk Falls
Character arcs are scripted; no opponent adapts to your choices
Dungeon Siege
Mobs charge on simple scripts
As Dusk Falls leans a little harder on variance, though the gap is small.
As Dusk Falls
Branching outcomes obscure which paths are accessible from current state
Dungeon Siege
Loot drops vary modestly
Dungeon Siege leans a little harder on optimization, though the gap is small.
As Dusk Falls
Understanding the branching tree allows deliberate replays toward target endings
Dungeon Siege
Party builds and pack-mule logistics are the game
