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
A cinematic puzzle platformer about sneaking a hapless Mudokon past guards while rescuing his coworkers.

Optimization · Practiced Mastery
A darker stealth-tinged Tomb Raider that sends a fugitive Lara through Paris and Prague.
Oddworld: Abe's Oddysee leans Optimization (Practiced Mastery); Tomb Raider: The Angel of Darkness 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.
Oddworld: Abe's Oddysee
Precise platforming and stealth timing kill instantly
Tomb Raider: The Angel of Darkness
Notoriously stiff controls make precise platforming harder than intended
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Sligs patrol on fixed scripts
Tomb Raider: The Angel of Darkness
No adaptive opponents exist
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Deterministic screens, no randomness
Tomb Raider: The Angel of Darkness
Levels and puzzles are entirely fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Oddworld: Abe's Oddysee
Mudokon rescue routes and puzzle solutions are solvable
Tomb Raider: The Angel of Darkness
Puzzle-solving, stat-gated paths, and route knowledge dominate
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.
