head to head
Super Mario Maker asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
Player-made platforming gauntlets where precision execution meets unseen level design.
Half-Life 2 leans Execution (Pure Mechanics); Super Mario Maker leans Execution (Pure Mechanics).
Super Mario Maker leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
Super Mario Maker
Community kaizo levels push platforming precision to extremes
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
Super Mario Maker
Levels are static once built; nothing adapts
Super Mario Maker leans clearly harder on variance.
Half-Life 2
Almost no randomness.
Super Mario Maker
Unknown user levels are hidden information until attempted
Super Mario Maker leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Super Mario Maker
Mastering tool tech and level conventions is learnable
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.
