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

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

Variance · Systems & Chaos
Co-op looting under randomised monster threats, testing careful handling and risk management.
Baldur's Gate 3 leans Optimization (Systems & Chaos); R.E.P.O. leans Variance (Systems & Chaos).
R.E.P.O. leans clearly harder on execution.
Baldur's Gate 3
Turn-based; no input dexterity.
R.E.P.O.
Physics-based carrying of fragile loot punishes clumsy hands
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.
R.E.P.O.
Monsters follow randomised scripts, not adaptive minds
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.
R.E.P.O.
Map layouts, loot and monster spawns are hidden each run
Baldur's Gate 3 leans clearly harder on optimization.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
R.E.P.O.
Route planning and extraction economy converge with experience
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.
