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

Optimization · Practiced Mastery
An action-command RPG where dodging and countering boss tells is half the battle.

Execution · Practiced Mastery
Open-galaxy entry whose mobile combat outshines its exploration loop.
Mario & Luigi: Bowser's Inside Story leans Optimization (Practiced Mastery); Mass Effect: Andromeda 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.
Mario & Luigi: Bowser's Inside Story
Every attack and dodge is a timed action command.
Mass Effect: Andromeda
jump-jet mobility raises the combat ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario & Luigi: Bowser's Inside Story
Boss tells are fixed and learnable.
Mass Effect: Andromeda
kett follow fixed AI routines
Mass Effect: Andromeda leans a little harder on variance, though the gap is small.
Mario & Luigi: Bowser's Inside Story
Little randomness beyond minor drops.
Mass Effect: Andromeda
exploration surprises only on first visit
Mario & Luigi: Bowser's Inside Story leans a little harder on optimization, though the gap is small.
Mario & Luigi: Bowser's Inside Story
Badges, gear, and learning attack patterns close fights.
Mass Effect: Andromeda
profile swapping and research crafting systems
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.
