head to head
Neither is simply harder - they are hard in different places. Baldur's Gate 3 demands more optimization; Lethal Company demands more execution.

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

Variance · Systems & Chaos
A co-op horror about scavenging scrap on hostile moons for a quota.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Lethal Company leans Variance (Systems & Chaos).
Lethal Company leans clearly harder on execution.
Baldur's Gate 3
Turn-based; no input dexterity.
Lethal Company
Movement and aim matter under pressure.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Lethal Company
Other players coordinate, but enemies scripted.
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.
Lethal Company
Moon layouts and monster spawns randomize.
Baldur's Gate 3 leans clearly harder on optimization.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Lethal Company
Quota routing and loadouts reward planning.
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.
