Portal 2Utawarerumono: Prelude to the Fallen
Axis by axis
Execution3 vs 1
Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
Utawarerumono: Prelude to the Fallen
Timed attack prompts add only a sliver of dexterity
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.
Utawarerumono: Prelude to the Fallen
Enemy AI follows fixed tactical scripts on a grid
Variance0 vs 2
Utawarerumono: Prelude to the Fallen leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
Utawarerumono: Prelude to the Fallen
Mild crit randomness inside otherwise deterministic battles
Optimization9 vs 7
Portal 2 leans clearly harder on optimization.
Portal 2
Solving the puzzle's logic IS the entire game.
Utawarerumono: Prelude to the Fallen
Grid positioning, unit builds and turn order are fully solvable
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.
