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 · Practiced Mastery
Lara raids Siberian tombs in a stealth-action adventure heavy on puzzles.

Execution · Practiced Mastery
The sequel-remake pairing Butcher Bay with a new stealth-action campaign aboard a mercenary ship.
Rise of the Tomb Raider leans Optimization (Practiced Mastery); The Chronicles of Riddick: Assault on Dark Athena leans Execution (Practiced Mastery).
The Chronicles of Riddick: Assault on Dark Athena leans a little harder on execution, though the gap is small.
Rise of the Tomb Raider
Bow aim, stealth timing, and platforming sequences.
The Chronicles of Riddick: Assault on Dark Athena
Melee takedowns and gunplay demand reliable hands
The Chronicles of Riddick: Assault on Dark Athena leans a little harder on reads, though the gap is small.
Rise of the Tomb Raider
Guards follow predictable patrol scripts.
The Chronicles of Riddick: Assault on Dark Athena
Drone and guard behavior is fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rise of the Tomb Raider
Tomb unknowns dissolve after one visit.
The Chronicles of Riddick: Assault on Dark Athena
First-run uncertainty about patrols and drone placements
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Rise of the Tomb Raider
Tomb puzzles, crafting, and collectible routing are solvable.
The Chronicles of Riddick: Assault on Dark Athena
Stealth routes and encounter solutions are learnable fixed content
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.
