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

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
Sea of Stars
Timed hits demand input precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Assassin's Creed Rogue
Stalker assassins ambush by script, not adaptation
Sea of Stars
Enemies are scripted.
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
Sea of Stars
Light combat 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
Sea of Stars
Combo and resource planning reward optimization.
