head to head
Super Mario Odyssey asks more than Guitar Hero II, and the gap is optimization.

Execution · Pure Mechanics
Sequel rhythm game with harder setlists and refined plastic-guitar technique.

Execution · Pure Mechanics
A 3D platformer whose joy lives in tight movement and capture-driven traversal.
Guitar Hero II leans Execution (Pure Mechanics); Super Mario Odyssey leans Execution (Pure Mechanics).
Guitar Hero II leans a little harder on execution, though the gap is small.
Guitar Hero II
Harder charts, hammer-ons, and three-note chords
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.
Guitar Hero II
Static note highways
Super Mario Odyssey
No adaptive opponents whatsoever.
Super Mario Odyssey leans a little harder on variance, though the gap is small.
Guitar Hero II
Fully deterministic charts
Super Mario Odyssey
Almost no randomness in level design.
Super Mario Odyssey leans clearly harder on optimization.
Guitar Hero II
Star power pathing for leaderboard play
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.
