head to head
Baldur's Gate 3 asks more than Divinity: Original Sin 2, and the gap is variance.

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

Optimization · Pure Optimization
A deeply optimizable tactical RPG where armor stripping and initiative manipulation produce near-deterministic victories.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Divinity: Original Sin 2 leans Optimization (Pure Optimization).
Divinity: Original Sin 2 leans a little harder on execution, though the gap is small.
Baldur's Gate 3
Turn-based; no input dexterity.
Divinity: Original Sin 2
Turn-based system demands zero reaction speed or motor precision
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.
Divinity: Original Sin 2
Multiplayer PvP arena adds light opponent-reading; solo is scripted
Baldur's Gate 3 leans clearly harder on variance.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Divinity: Original Sin 2
Source point limits and hidden enemy armor values create unknowns
Divinity: Original Sin 2 leans a little harder on optimization, though the gap is small.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Divinity: Original Sin 2
Lone Wolf builds and damage-type stacking define solved optimal strategies
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.
