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.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Practiced Mastery
A Gothic-style open-world RPG on a volcanic island where build and faction choices shape a harsh adventure.
Fallout: New Vegas leans Optimization (Pure Optimization); Risen leans Optimization (Practiced Mastery).
Risen leans a little harder on execution, though the gap is small.
Fallout: New Vegas
Shooter inputs with VATS assist
Risen
Stamina-based melee with timing and dodges matters early
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Scripted factions and enemies
Risen
Enemy AI follows fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Some loot and crit RNG
Risen
Some loot rolls; world is mostly hand-placed
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Risen
Faction choice, build, and quest routing dominate
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.
