head to head
Super Mario Odyssey asks more than Rock Band 4, and the gap is optimization.

Execution · Pure Mechanics
The modern Rock Band keeping plastic-instrument band night alive with a huge DLC library.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Rock Band 4 leans Execution (Pure Mechanics); Super Mario Odyssey 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.
Rock Band 4
Instrument accuracy remains the entire test
Super Mario Odyssey
Precise platforming and capture-move tech ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rock Band 4
No adaptive opponent
Super Mario Odyssey
No adaptive opponents whatsoever.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rock Band 4
Freestyle solos add slight improvisational looseness
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans clearly harder on optimization.
Rock Band 4
Overdrive pathing and chart familiarity
Super Mario Odyssey
Moon routes and movement tech learnable.
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.
