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
A roguelike souls-like where adapting builds to randomized runs matters as much as combat skill.

Optimization · Practiced Mastery
Remake of the original Risk of Rain with new survivors and tighter action.
Elden Ring Nightreign leans Execution (Practiced Mastery); Risk of Rain Returns leans Optimization (Practiced Mastery).
Elden Ring Nightreign leans a little harder on execution, though the gap is small.
Elden Ring Nightreign
precise dodge and attack timing required
Risk of Rain Returns
Platforming and aiming demand sharper inputs than original.
Elden Ring Nightreign leans a little harder on reads, though the gap is small.
Elden Ring Nightreign
bosses are fixed scripted patterns
Risk of Rain Returns
Scripted enemy behaviour throughout.
Risk of Rain Returns leans a little harder on variance, though the gap is small.
Elden Ring Nightreign
run seeds and loot are randomized
Risk of Rain Returns
Random item pool defines builds run to run.
Risk of Rain Returns leans a little harder on optimization, though the gap is small.
Elden Ring Nightreign
builds and run strategy are solvable
Risk of Rain Returns
Survivor kits and routing reward 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.
