head to head
Baldur's Gate 3 asks more than Fallout 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 post-nuclear RPG expanded in scope where tagged builds and Gifted-trait optimization dominate.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Fallout 2 leans Optimization (Pure Optimization).
Fallout 2 leans a little harder on execution, though the gap is small.
Baldur's Gate 3
Turn-based; no input dexterity.
Fallout 2
Turn-based AP system makes twitch entirely irrelevant
Baldur's Gate 3 leans a little harder on reads, though the gap is small.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Fallout 2
All tribal and Enclave enemies run fixed scripted combat routines
Baldur's Gate 3 leans clearly harder on variance.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Fallout 2
Hidden special encounters and timed events create significant unknown-information space
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Fallout 2
SPECIAL and skill tagging with Gifted trait produce well-known dominant build 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.
