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

Navigating hand-painted levels in rhythm with fixed musical hazard patterns.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
Beatbuddy: Tale of the Guardians leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).

Beatbuddy: Tale of the Guardians
Moving and dodging on the beat carries every section
Red Dead Redemption 2

Beatbuddy: Tale of the Guardians
Hazards pulse to fixed musical patterns
Red Dead Redemption 2

Levels and rhythms are fully deterministic
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.

Beatbuddy: Tale of the Guardians
Puzzle rooms and route memory add a light systems layer
Red Dead Redemption 2
Loadouts and routes solvable but loose.
