head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

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

Optimization · Practiced Mastery
Planning stealth routes and psychic-power use through scripted guard patrols.
Rise of the Tomb Raider leans Optimization (Practiced Mastery); Second Sight 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.
Second Sight
Aiming and psychic-power juggling under fire need moderate hands
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.
Second Sight
Guard AI runs predictable patrol scripts
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.
Second Sight
Patrol routes are unknown only on first pass
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.
Second Sight
Planning stealth routes and power usage solves each level
