head to head
Blockout asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Execution · Practiced Mastery
Tetris extended into 3D - spatial packing optimization executed under accelerating pressure.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.
Blockout leans Execution (Practiced Mastery); Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery).
Blockout leans clearly harder on execution.
Blockout
Rotating polycubes on three axes under time pressure strains hands
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
Solo pit - nothing to predict
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
Piece sequence is random but quickly bounded
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
3D packing has optimal layer-clearing patterns to internalise
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
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.
