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

Execution · Practiced Mastery
A cinematic open-world western leaning on shooting feel and atmosphere.

Execution · Practiced Mastery
An open-structured Game Boy Mario where six zones guard coins that unlock Wario's castle.
Red Dead Redemption 2 leans Execution (Practiced Mastery); Super Mario Land 2: 6 Golden Coins leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Red Dead Redemption 2
Gunplay and Dead Eye reward aim and timing.
Super Mario Land 2: 6 Golden Coins
Forgiving jumps but bosses still test timing
Red Dead Redemption 2 leans a little harder on reads, though the gap is small.
Red Dead Redemption 2
Enemies use scripted AI patterns, not adaptation.
Super Mario Land 2: 6 Golden Coins
No adaptive opposition anywhere
Red Dead Redemption 2 leans a little harder on variance, though the gap is small.
Red Dead Redemption 2
Some hunting and weather randomness, lightly hidden.
Super Mario Land 2: 6 Golden Coins
Secret exits hidden until discovered
Super Mario Land 2: 6 Golden Coins leans a little harder on optimization, though the gap is small.
Red Dead Redemption 2
Loadouts and routes solvable but loose.
Super Mario Land 2: 6 Golden Coins
Nonlinear zone order and secret levels reward planning
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.
