Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

A dialogue RPG resolved by stat builds against dice checks.

Optimization · Pure Optimization
A solvable type-matchup system wrapped in collection and light RNG.

Pokémon Blue Version
Type chart and team building make the campaign solvable
