head to head
Baldur's Gate 3 asks more than Sunless Sea, and the gap is optimization.

Optimization · Systems & Chaos
A D&D CRPG where build optimization and dice variance dominate every encounter.

Variance · Systems & Chaos
A gothic exploration roguelike about sailing an underground ocean, trading terror for stories and profit.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Sunless Sea leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate 3
Turn-based; no input dexterity.
Sunless Sea
Slow boat combat barely tests the hands
Baldur's Gate 3 leans clearly harder on reads.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Sunless Sea
Horrors are scripted or random, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Sunless Sea
Hidden map, random events and unknown story branches dominate
Baldur's Gate 3 leans clearly harder on optimization.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Sunless Sea
Trade routes and fuel math converge once mapped
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.
