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

Execution · Pure Mechanics
An arcade beat 'em up testing crowd-control reflexes and memorised spawn patterns.

Execution · Pure Mechanics
A hand-animated revival of Rayman's 2D platforming.
Alien Storm leans Execution (Pure Mechanics); Rayman Origins leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Storm
Arcade crowd control and dodge timing decide credits spent
Rayman Origins
Fluid run-jump-glide chains
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Storm
Alien waves follow fixed arcade scripts
Rayman Origins
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Storm
Enemy ambush spots are memorisable after one run
Rayman Origins
Deterministic levels
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Storm
Energy management and learned spawn patterns reward repetition
Rayman Origins
Lum routing for perfection
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.
