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 · Pure Mechanics
A physics-based wrestling brawler about controlling ragdoll combat against opponents.

Execution · Competitive PvP
Late-90s arcade football execution with couch-versus prediction and bouncy luck.
Drunken Wrestlers 2 leans Execution (Pure Mechanics); FIFA 99 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Drunken Wrestlers 2
physics-based ragdoll control precision
FIFA 99
Quick passing and shot timing in arcade-leaning football
FIFA 99 leans a little harder on reads, though the gap is small.
Drunken Wrestlers 2
predicting human opponent's wrestling moves
FIFA 99
Couch opponents can be conditioned and baited
FIFA 99 leans a little harder on variance, though the gap is small.
Drunken Wrestlers 2
physics ragdoll randomness affects outcomes
FIFA 99
Era physics produce regular fluke goals
FIFA 99 leans a little harder on optimization, though the gap is small.
Drunken Wrestlers 2
minimal, mostly reflexive physical play
FIFA 99
Simple formations and known exploit angles map fast
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.
