Execution · Pure Mechanics
A high-intensity wave shooter testing sustained accuracy and stamina against unrelenting scripted enemy hordes.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.

Axis by axis
Execution8 vs 8

Serious Sam 3: BFE
Iron-sights mechanics add precision demand on top of classic crowd control
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.
Serious Sam 3: BFE
All enemies follow scripted wave patterns throughout the campaign
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.
Serious Sam 3: BFE
Encounter layout is consistent and fully learnable after one pass
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.
Serious Sam 3: BFE
Weapon economy and grenade usage offer a thin planning layer
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.
