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
An early top-down rampage shooter with simple execution demands.

Execution · Practiced Mastery
A survival-horror action game where managing scarce resources against scripted horrors is key.
Postal leans Execution (Practiced Mastery); Resident Evil 3 leans Execution (Practiced Mastery).
Resident Evil 3 leans a little harder on execution, though the gap is small.
Postal
top-down shooting and movement
Resident Evil 3
aim and dodge timing against threats
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
enemies use fixed aggressive scripts
Resident Evil 3
Nemesis is scripted, not truly adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Postal
enemy spawn and pathing randomness
Resident Evil 3
item and enemy spawn randomness
Resident Evil 3 leans a little harder on optimization, though the gap is small.
Postal
weapon choice and route clearing
Resident Evil 3
resource management and routing solvable
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.
