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
An open-world stealth-action game where a turncoat assassin hunts his old brotherhood across the North Atlantic.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Assassin's Creed Rogue leans Optimization (Practiced Mastery); Grand Theft Auto: San Andreas 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.
Assassin's Creed Rogue
Forgiving parkour and counter-heavy combat ask little
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Assassin's Creed Rogue leans a little harder on reads, though the gap is small.
Assassin's Creed Rogue
Stalker assassins ambush by script, not adaptation
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Rogue
Some naval weather and patrol noise
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Rogue
Ship upgrades, fleet economy, and collectible routing dominate
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
