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
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.

Execution · Pure Mechanics
A classic arcade shmup testing dodging reflexes against memorised enemy waves.
Crash Bandicoot leans Execution (Pure Mechanics); Mega Force 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.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Mega Force
Perfect dodging and shooting would clear every wave alone
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Hazards are fixed patterns
Mega Force
Enemy waves are scripted, nothing adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Everything scripted and placed
Mega Force
Spawn patterns repeat identically and map quickly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Box routes and gem requirements are learnable
Mega Force
Memorising wave order and scoring spots maximises runs
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.
