Final Fantasy XIV
Very little RNG in core content
Portal 2

Final Fantasy XIV
Rotations and raid solves are theorycraft puzzles
Portal 2
Solving the puzzle's logic IS the entire game.
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.
