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
An isometric action RPG narrated as you play.

Optimization · Practiced Mastery
Lara raids Siberian tombs in a stealth-action adventure heavy on puzzles.
Bastion leans Optimization (Practiced Mastery); Rise of the Tomb Raider 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.
Bastion
Action combat needs timing and aim.
Rise of the Tomb Raider
Bow aim, stealth timing, and platforming sequences.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Enemies are scripted.
Rise of the Tomb Raider
Guards follow predictable patrol scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Minor loot variance.
Rise of the Tomb Raider
Tomb unknowns dissolve after one visit.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bastion
Weapon and idol builds reward planning.
Rise of the Tomb Raider
Tomb puzzles, crafting, and collectible routing are solvable.
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.
