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

A vibrant 2D platformer with rhythm-based highlight levels.

Execution · Pure Mechanics
Top-down run-and-gun testing aim and memorised level knowledge from a movie license.

Rayman Legends
Tight 2D platforming and music levels
True Lies
Top-down aim and dodging carry every firefight
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rayman Legends

True Lies
Goons follow simple fixed attack scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rayman Legends
Fixed levels
True Lies
Enemy placements repeat identically each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
