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.

Execution · Practiced Mastery
Roguelike soulslike shooter with deep builds.

Optimization · Practiced Mastery
A co-op third-person looter shooter where module build optimisation and drop variance define long-term progression.
Remnant II leans Execution (Practiced Mastery); The First Descendant leans Optimization (Practiced Mastery).
Remnant II leans a little harder on execution, though the gap is small.
Remnant II
Soulslike dodges with gunplay timing
The First Descendant
Colossus boss fights and intercept missions require dodge timing and aim
Remnant II leans a little harder on reads, though the gap is small.
Remnant II
Bosses scripted, not adaptive
The First Descendant
PvE co-op throughout with no meaningful adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Remnant II
Procedural worlds and gear rolls vary
The First Descendant
Module drop RNG and Descendant unlock rates drive the grind
The First Descendant leans a little harder on optimization, though the gap is small.
Remnant II
Archetype builds and mod synergies deep
The First Descendant
Module builds and Descendant loadouts are extensively theory-crafted
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.
