head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

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

Optimization · Practiced Mastery
The sequel takes Torque to Baltimore to fight slavery-themed monsters while his morality shapes the story.
Rise of the Tomb Raider leans Optimization (Practiced Mastery); The Suffering: Ties That Bind leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Rise of the Tomb Raider
Bow aim, stealth timing, and platforming sequences.
The Suffering: Ties That Bind
Gunplay and monster-form brawling demand decent reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rise of the Tomb Raider
Guards follow predictable patrol scripts.
The Suffering: Ties That Bind
Enemy archetypes run scripted behaviour, never adapt
The Suffering: Ties That Bind leans a little harder on variance, though the gap is small.
Rise of the Tomb Raider
Tomb unknowns dissolve after one visit.
The Suffering: Ties That Bind
Unknown encounters and branching morality first time
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 Suffering: Ties That Bind
Combat systems and morality routes converge with knowledge
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.
