12 is Better Than 6 leans Execution (Practiced Mastery); Hotline Miami leans Execution (Practiced Mastery).
Hotline Miami leans a little harder on execution, though the gap is small.
12 is Better Than 6
One-hit deaths, manual cocking, fast top-down aim
Hotline Miami

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Hotline Miami
Enemies are dumb scripted reactors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
12 is Better Than 6
Unknown enemy placements on first attempts only
Hotline Miami
Slight enemy behavior wobble between restarts
Hotline Miami leans a little harder on optimization, though the gap is small.
12 is Better Than 6
Each room becomes a learnable clear order
Hotline Miami
Route planning and mask choice per floor
