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.

Optimization · Practiced Mastery
Deck-folder optimisation executed through real-time grid dodging.

Optimization · Pure Optimization
An immersive-sim RPG demanding intricate build optimisation and resource management aboard a hostile alien-infested starship.
Mega Man Battle Network 3 Blue leans Optimization (Practiced Mastery); System Shock 2 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man Battle Network 3 Blue
Grid dodging and chip timing in real time demand reflexes
System Shock 2
Weapon degradation and limited stats moderate the raw aim ceiling
Mega Man Battle Network 3 Blue leans a little harder on reads, though the gap is small.
Mega Man Battle Network 3 Blue
Viruses and bosses follow learnable patterns; link battles are rare
System Shock 2
All enemies are scripted with fixed patrol and attack routines
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mega Man Battle Network 3 Blue
Random chip draws shape each battle's options
System Shock 2
Random loot locations and psi powers introduce run-to-run variance
System Shock 2 leans a little harder on optimization, though the gap is small.
Mega Man Battle Network 3 Blue
Folder construction and style builds dominate outcomes
System Shock 2
Deep build tree and resource conservation define the entire skill ceiling
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.
