head to head
Postal asks more than Hong Kong 97, and the gap is optimization.

Execution · Twitch Chaos
A notoriously broken shooter testing nothing but tolerance and basic bullet dodging.

Execution · Practiced Mastery
An early top-down rampage shooter with simple execution demands.
Hong Kong 97 leans Execution (Twitch Chaos); Postal 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.
Hong Kong 97
Dodging bullet spam with one-hit deaths is the only skill present
Postal
top-down shooting and movement
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hong Kong 97
Enemies spawn in mindless waves
Postal
enemies use fixed aggressive scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hong Kong 97
Spawn patterns have slight randomness
Postal
enemy spawn and pathing randomness
Postal leans clearly harder on optimization.
Hong Kong 97
There is almost no system to optimise
Postal
weapon choice and route clearing
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.
