head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Deeper sequel turning occupied-Europe missions into intricate solvable stealth puzzles.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Commandos 2: Men of Courage leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Commandos 2: Men of Courage leans a little harder on execution, though the gap is small.
Commandos 2: Men of Courage
Multi-commando coordination under timing windows
Portal 2
Portal placement requires some precision but timing is lenient.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 2: Men of Courage
Scripted patrols with no adaptation
Portal 2
No opponent; puzzles are static.
Commandos 2: Men of Courage leans a little harder on variance, though the gap is small.
Commandos 2: Men of Courage
Vision cones shown; layouts fixed
Portal 2
Puzzles are deterministic with no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Commandos 2: Men of Courage
Open-ended missions still reduce to solved routes
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.
