Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
Xenonauts
Turn-based; no physical demands.
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.
Xenonauts
Alien AI follows consistent behavior rules.
Variance0 vs 6
Xenonauts leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
Xenonauts
Hit rolls and unseen alien positions punish certainty.
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
Solving the puzzle's logic IS the entire game.
Xenonauts
Air war, economy and squad doctrine decide campaigns.
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.
