Building comparison
head to head
Once HumanvsRogue Legacy 2
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Once Human
Optimization · Practiced Mastery
Progressing through a contaminated open world by solving its scenario tech tree and optimising base builds.
Rogue Legacy 2
Optimization · Practiced Mastery
A tighter sequel that raises execution demands while deepening the build and meta-progression systems.
Once Human leans Optimization (Practiced Mastery); Rogue Legacy 2 leans Optimization (Practiced Mastery).

Axis by axis
Execution5 vs 6
Rogue Legacy 2 leans a little harder on execution, though the gap is small.
Once Human
Third-person shooting and dodge rolls require real aim and timing
Rogue Legacy 2
More demanding platforming and combat than the original
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Once Human
Deviant creatures follow scripted attack patterns only
Rogue Legacy 2
All enemies follow learned scripted patterns
Variance5 vs 5
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Once Human
Deviant spawn composition and loot tables carry meaningful randomness
Rogue Legacy 2
Class randomisation and relic pools create divergent runs
Optimization7 vs 7
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Once Human
Scenario tech tree, base construction, and gear crafting are solvable
Rogue Legacy 2
Heirloom upgrades and class mastery form a deep meta-progression system
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.
