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
Greek-flavored action RPG where build-crafting drives long-haul play.

Optimization · Practiced Mastery
A retro-styled turn-based RPG about two solstice warriors.
Assassin's Creed Odyssey leans Optimization (Practiced Mastery); Sea of Stars 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 Odyssey
Parry and dodge timing required, not punishing.
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 Odyssey
Mercenary AI scripted, not adaptive.
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 Odyssey
Loot tiers and mercenary spawns randomized.
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 Odyssey
Engravings, gear sets, builds deeply solvable.
Sea of Stars
Combo and resource planning reward optimization.
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.
