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 neo-noir one-hit-kill action platformer about planning and replaying perfect assassinations.

Execution · Practiced Mastery
Executing memorised high-speed routes through deterministic platforming levels.
Katana ZERO leans Execution (Practiced Mastery); Sonic Generations leans Execution (Practiced Mastery).
Katana ZERO leans a little harder on execution, though the gap is small.
Katana ZERO
One-hit-death slashing and deflects demand precision
Sonic Generations
Holding speed through precise jumps and boosts is the test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Katana ZERO
Enemies follow fixed placements and behaviours
Sonic Generations
No opponent; bosses are fixed patterns
Katana ZERO leans a little harder on variance, though the gap is small.
Katana ZERO
Rooms are identical on every attempt
Sonic Generations
Levels are fully deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Katana ZERO
Planning the perfect room-clear sequence
Sonic Generations
S-ranks come from memorising optimal routes and shortcuts
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.
