Half-Life 2vsTetris Effect
Tetris Effect asks more than Half-Life 2, and the gap is execution.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.
Half-Life 2 leans Execution (Pure Mechanics); Tetris Effect leans Execution (Pure Mechanics).

Axis by axis
Execution6 vs 8
Tetris Effect leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
Tetris Effect
Piece placement under speed and Zone timing is the whole test
Reads1 vs 0
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
Tetris Effect
Solo experience with no opponent to model
Variance1 vs 2
Tetris Effect leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
Tetris Effect
Randomised bag is bounded and quickly mappable
Optimization3 vs 4
Tetris Effect leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Tetris Effect
Stacking theory and Zone usage have known optimal lines
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.
