head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Survival planning and base economics wrapped around modest stealth shooting.

Optimization · Practiced Mastery
Methodically mapping a hostile station where knowledge and routing beat reflexes.
Chernobylite leans Optimization (Practiced Mastery); System Shock leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Chernobylite
Stealth and gunplay matter but are forgiving
System Shock
Combat and cyberspace ask competent but dated reflexes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chernobylite
Enemies are scripted patrols, not adaptive minds
System Shock
SHODAN's threats are scripted, not an adapting mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chernobylite
Mission events and world states shift between days
System Shock
Citadel's layout and logs are hidden until uncovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Chernobylite
Base building, companion management and resource planning dominate
System Shock
Inventory, routing and station knowledge solve the game
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.
