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
Side-scrolling stealth that rewards memorising patrols and executing clean routes.

Optimization · Practiced Mastery
The streamlined modern reboot of classic Lara, light on every axis but optimization.
Assassin's Creed Chronicles: China leans Optimization (Practiced Mastery); Tomb Raider: Legend 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.
Assassin's Creed Chronicles: China
Stealth timing and climb precision punish sloppiness
Tomb Raider: Legend
Modernized grapple platforming with forgiving timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Chronicles: China
Guard patrols are fixed memorisable loops
Tomb Raider: Legend
Scripted mercenaries pose no adaptive threat
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Chronicles: China
Everything is scripted and visible with study
Tomb Raider: Legend
Linear levels leave little hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Chronicles: China
Routing perfect-stealth paths through guard patterns is the score game
Tomb Raider: Legend
