head to head
Lost Ark asks more than System Shock 2, and the gap is reads.

Optimization · Pure Optimization
An ARPG-MMO blending action execution with brutal gear optimization.

Optimization · Pure Optimization
An immersive-sim RPG demanding intricate build optimisation and resource management aboard a hostile alien-infested starship.
Lost Ark leans Optimization (Pure Optimization); 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.
Lost Ark
Action combat demands mechanical precision
System Shock 2
Weapon degradation and limited stats moderate the raw aim ceiling
Lost Ark leans clearly harder on reads.
Lost Ark
Raid bosses are scripted
System Shock 2
All enemies are scripted with fixed patrol and attack routines
System Shock 2 leans a little harder on variance, though the gap is small.
Lost Ark
Honing and gear RNG is notorious
System Shock 2
Random loot locations and psi powers introduce run-to-run variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Ark
Build, engravings, and rotations near-solved
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.
