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

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

Optimization · Systems & Chaos
Racing the day cycle to stack items faster than the seed punishes you.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Muck leans Optimization (Systems & Chaos).
Muck leans clearly harder on execution.
Baldur's Gate 3
Turn-based; no input dexterity.
Muck
Kiting bosses and dodging demands basic action skill
Baldur's Gate 3 leans clearly harder on reads.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Muck
Enemies swarm on simple scripts
Baldur's Gate 3 leans clearly harder on variance.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Muck
Seeds, chest rolls and item drops shape every run
Baldur's Gate 3 leans clearly harder on optimization.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Muck
Power-stacking economy and day-loop routing decide survival
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.
