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
Open-world survival action about outrunning massive zombie hordes on a motorcycle.

Optimization · Practiced Mastery
Routing guard patrols and executing clean stealth kills through fixed missions.
Days Gone leans Optimization (Practiced Mastery); Tenchu Z 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.
Days Gone
horde shooting and bike handling under pressure
Tenchu Z
Stealth-kill timing and movement control matter but forgive
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Days Gone
freaker AI is scripted swarm logic
Tenchu Z
Guard patrols are scripted, mappable routes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Days Gone
patrols and weather shift encounters slightly
Tenchu Z
Patrol routes are unknown only on first attempts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Days Gone
horde routing, traps, and gear prep decide fights
Tenchu Z
Routing each mission for undetected kills is the real game
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.
