head to head
Super Mario Odyssey asks more than Um Jammer Lammy, and the gap is optimization.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.

Execution · Pure Mechanics
PaRappa spinoff guitar rhythm game with famously strict and slippery timing judgment.
Super Mario Odyssey leans Execution (Pure Mechanics); Um Jammer Lammy 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.
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Um Jammer Lammy
Loose timing windows punish imprecise guitar inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
No adaptive opponents whatsoever.
Um Jammer Lammy
Call-and-response lines are scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Odyssey
Almost no randomness in level design.
Um Jammer Lammy
Fixed songs, ad-lib scoring slightly opaque
Super Mario Odyssey leans clearly harder on optimization.
Super Mario Odyssey
Moon routes and movement tech learnable.
Um Jammer Lammy
Freestyle Cool-mode lines can be crafted and learned
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.
