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.

Execution · Practiced Mastery
Modern 2D Mario platformer built on classic jump precision and hidden exits.

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.
New Super Mario Bros. leans Execution (Practiced Mastery); Red Dead Redemption 2 leans Execution (Practiced Mastery).
New Super Mario Bros. leans a little harder on execution, though the gap is small.
New Super Mario Bros.
Jump timing and momentum control carry every level
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
New Super Mario Bros.
Enemies follow fixed scripted patterns
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
New Super Mario Bros.
Levels fully deterministic once seen
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
New Super Mario Bros. leans a little harder on optimization, though the gap is small.
New Super Mario Bros.
Secret exits, star coins, and route knowledge
Red Dead Redemption 2
Loadouts and routes solvable but loose.
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.
