A swipe-em-up arcade game where slicing accuracy against random fruit spawns is the whole skill.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Fruit Ninja leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Fruit Ninja leans a little harder on execution, though the gap is small.
Fruit Ninja
Swipe accuracy and combo timing
Half-Life 2
Gravity gun and shooting demand precision.
Half-Life 2 leans a little harder on reads, though the gap is small.
Fruit Ninja
No opponent
Half-Life 2
Combine AI scripted, non-adaptive.

Fruit Ninja
Combo and crit systems are shallow but real
Half-Life 2
Linear progression with no builds.
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.
