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 chaotic co-op platformer mixing precise jumps with friendly betrayal.

Execution · Pure Mechanics
Precise jump execution across fixed levels with secrets to memorise.
BattleBlock Theater leans Execution (Practiced Mastery); Super Mario World leans Execution (Pure Mechanics).
Super Mario World leans a little harder on execution, though the gap is small.
BattleBlock Theater
Precise jumps and tosses under pressure.
Super Mario World
Perfect inputs trivialise every jump, spin and cape flight
BattleBlock Theater leans a little harder on reads, though the gap is small.
BattleBlock Theater
Versus mode adds light human chaos.
Super Mario World
Scripted Koopas adapt to nothing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
BattleBlock Theater
Levels fixed.
Super Mario World
Levels are fixed; nothing hidden survives one playthrough
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
BattleBlock Theater
Gem routes and weapon picks learnable.
Super Mario World
Secret exits and route knowledge add a modest solvable layer
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.
