ALTF4vsTetris Effect
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.
ALTF4
Execution · Pure Mechanics
A permadeath precision runner about clearing trap-filled levels in one go.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.
ALTF4 leans Execution (Pure Mechanics); Tetris Effect leans Execution (Pure Mechanics).
ALTF4Tetris Effect
Axis by axis
Execution8 vs 8
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
ALTF4
Permadeath precision movement through traps is the entire test
Tetris Effect
Piece placement under speed and Zone timing is the whole test
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
ALTF4
Solo runner, no opponent
Tetris Effect
Solo experience with no opponent to model
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
ALTF4
Traps fixed once learned
Tetris Effect
Randomised bag is bounded and quickly mappable
Optimization4 vs 4
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
ALTF4
Memorising trap layouts and clean lines through them
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.
