Portal 2vsRelicta
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Portal 2
Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Relicta
Optimization · Pure Optimization
Deterministic physics puzzles solved by reasoning about magnetism and gravity.
Portal 2 leans Optimization (Pure Optimization); Relicta leans Optimization (Pure Optimization).
Portal 2Relicta
Axis by axis
Execution3 vs 2
Portal 2 leans a little harder on execution, though the gap is small.
Portal 2
Portal placement requires some precision but timing is lenient.
Relicta
Walking between switches; timing rarely matters
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.
Relicta
No adversary in the puzzle chambers
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
Puzzles are deterministic with no randomness.
Relicta
Every chamber is fully visible and deterministic
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.
Relicta
Magnetism-gravity logic chains are 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.
