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 · Pure Mechanics
A loud, high-endurance test of accurate crowd control against relentless scripted enemy swarms in open arenas.

Execution · Pure Mechanics
An intense bullet-dense shoot-em-up testing reflexes and dodging precision.
Serious Sam: The First Encounter leans Execution (Pure Mechanics); Summer Carnival '92: Recca leans Execution (Pure Mechanics).
Summer Carnival '92: Recca leans a little harder on execution, though the gap is small.
Serious Sam: The First Encounter
Sustained accurate fire against enormous enemy hordes demands constant aim
Summer Carnival '92: Recca
Extreme bullet density makes dodging and aim everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Serious Sam: The First Encounter
All enemies are scripted and follow fixed rush patterns
Summer Carnival '92: Recca
Enemies follow scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Serious Sam: The First Encounter
Enemy placement is consistent across runs; no hidden information
Summer Carnival '92: Recca
Patterns are fixed once learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Serious Sam: The First Encounter
Enemy priority and positioning strategy are learnable but shallow
Summer Carnival '92: Recca
Weapon selection and route memorization aid survival
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.
