head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
A retro Sonic revival celebrating classic-era momentum design.

Execution · Practiced Mastery
A co-op adventure that relentlessly cycles through genres, demanding precise execution and partner synchronisation in each new mechanical context.
Sonic Mania leans Execution (Practiced Mastery); Split Fiction leans Execution (Practiced Mastery).
Sonic Mania leans a little harder on execution, though the gap is small.
Sonic Mania
High-speed reaction platforming
Split Fiction
Constant mechanical shifts demand fast adaptation and precise inputs
Split Fiction leans a little harder on reads, though the gap is small.
Sonic Mania
No human opponent
Split Fiction
Co-op partner coordination involves light social reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Mania
Mostly deterministic with hidden routes
Split Fiction
Genre-shifting levels introduce some unknown obstacles per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Sonic Mania
Route knowledge dominates speedruns
Split Fiction
Each world's mechanics reward mastering the optimal movement path
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.
