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
A rhythm racer that turns any music file into a reflex puzzle track.

Execution · Pure Mechanics
Pioneering wireframe arcade tank combat fought in first-person vector graphics.
Audiosurf leans Execution (Pure Mechanics); Battlezone 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.
Audiosurf
Lane-switching to the beat tests reaction speed.
Battlezone
Tank aim and dodge timing under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
No opponent.
Battlezone
Enemy tanks follow simple fixed routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Track generated from song, then fixed.
Battlezone
Enemy spawn positions vary run to run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Block-matching color strategy learnable per song.
Battlezone
Learning enemy behavior and scoring patterns
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.
