Portal 2Stardew Valley
Axis by axis
Execution3 vs 1
Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
Stardew Valley
Trivial timing on fishing and combat
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
Stardew Valley
No adaptive opponent exists
Variance0 vs 3
Stardew Valley leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
Stardew Valley
Crop luck and geode RNG matter modestly
Optimization9 vs 8
Portal 2 leans a little harder on optimization, though the gap is small.
Portal 2
Solving the puzzle's logic IS the entire game.
Stardew Valley
Routing seasons, profit loops, and bundles dominates
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.
