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

Execution · Practiced Mastery
A basic arcade soccer game testing input timing and simple positioning.

Execution · Practiced Mastery
A co-op puzzle-platformer that tests physical coordination and communication across a wide variety of co-designed mechanics.
Champions World Class Soccer leans Execution (Practiced Mastery); It Takes Two leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Champions World Class Soccer
Passing, shooting and tackling timing carry every play
It Takes Two
Co-op platforming demands tight timing, coordination, and spatial precision
Champions World Class Soccer leans a little harder on reads, though the gap is small.
Champions World Class Soccer
Two-player mode lets you predict a human opponent
It Takes Two
Human partner requires some coordination reads but not competitive prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Champions World Class Soccer
Little randomness once team ratings are known
It Takes Two
Puzzle solutions are fixed; little hidden randomness
It Takes Two leans a little harder on optimization, though the gap is small.
Champions World Class Soccer
Formation choice and team selection give a known edge
It Takes Two
Each chapter has an optimal movement approach once mechanics are learned
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.
