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.

Optimization · Practiced Mastery
Tests routing an ever-growing ball through fixed stages against the clock.

Optimization · Practiced Mastery
A darkly comic action game where you herd colour-coded minion hordes as an evil overlord.
Me & My Katamari leans Optimization (Practiced Mastery); Overlord leans Optimization (Practiced Mastery).
Me & My Katamari leans a little harder on execution, though the gap is small.
Me & My Katamari
Awkward PSP rolling controls demand constant steering effort
Overlord
Sweeping minion hordes takes modest dexterity
Overlord leans a little harder on reads, though the gap is small.
Me & My Katamari
Objects and people never adapt to the ball
Overlord
Scripted heroes and creatures
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Me & My Katamari
Object layouts are fixed per stage
Overlord
Fixed level design
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Me & My Katamari
Size-growth routing per stage has learnable optimal paths
Overlord
Minion type usage and upgrade economy reward planning
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.
