Sonic Adventure DX: Director's Cut
Execution · Practiced Mastery
Wrangling high-speed 3D movement through fixed stages and boss scripts.

Marble Skies
precise marble control through 3D courses
Sonic Adventure DX: Director's Cut
High-speed 3D control and jank-wrangling demand real hands
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Marble Skies
no opponent, solo time-trial platforming
Sonic Adventure DX: Director's Cut
Chaos bosses run fixed phase scripts
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Sonic Adventure DX: Director's Cut
Stage layouts and upgrades never change
Optimization3 vs 4
Sonic Adventure DX: Director's Cut leans a little harder on optimization, though the gap is small.
Marble Skies
route memorization for best times
Sonic Adventure DX: Director's Cut
Speedrun routing and A-rank paths are learnable systems
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.
