head to head
Neither is simply harder - they are hard in different places. Baldur's Gate 3 demands more variance; Pokemon Stadium 2 demands more reads.

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

Optimization · Systems & Chaos
N64 arena battler where rental and imported Pokemon fight in 3D tournaments and mini-games.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Baldur's Gate 3
Turn-based; no input dexterity.
Pokemon Stadium 2
Menu-driven turn battles; no physical demands
Pokemon Stadium 2 leans clearly harder on reads.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Pokemon Stadium 2
Human PvP cups reward prediction; AI cups are mappable
Baldur's Gate 3 leans clearly harder on variance.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Pokemon Stadium 2
Accuracy rolls, crits, rental rosters add randomness
Baldur's Gate 3 leans clearly harder on optimization.

Builds, party comp, action economy fully solvable.
Pokemon Stadium 2
Team building, movesets, type matchups are solvable
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.
