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

A match-three puzzle about planning rune swaps to clear themed wonder boards.

Optimization · Pure Optimization
Capcom's survival horror where you manage scarce ammo while raptors hunt you through a research facility.

Quick swaps under time pressure matter somewhat
Dino Crisis
Tank-control dodging of fast raptors punishes slow hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
7 Wonders of the Ancient World
Solo match-three, no opponent to predict
Dino Crisis
Dinosaur AI is aggressive but fixed, never models you

Dino Crisis
Ambush placements and item locations are unknown first time
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
