Turn-based; no physical demands
Portal 2
Portal placement requires some precision but timing is lenient.
Hard West leans a little harder on reads, though the gap is small.

Luck meter tames RNG but cards and shots vary
Portal 2

Portal 2 leans a little harder on optimization, though the gap is small.
Hard West
Positioning, ability combos, and luck-system math dominate
Portal 2
Solving the puzzle's logic IS the entire game.
