Axis by axis
Execution3 vs 1
Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
SimCity
Pause-friendly building removes any physical test
Reads0 vs 1
SimCity leans a little harder on reads, though the gap is small.
Portal 2
No opponent; puzzles are static.
SimCity
Region multiplayer is cooperative, not adversarial prediction
Variance0 vs 2
SimCity leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
SimCity
Disasters and agent simulation quirks add mild randomness
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.
SimCity
Zoning, traffic flow and specialisation economies are the whole 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.
