head to head
Portal 2 asks more than Star Fox Adventures, and the gap is optimization.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.

Optimization · Pure Optimization
Zelda-style puzzle dungeons and exploration with low-pressure combat.
Portal 2 leans Optimization (Pure Optimization); Star Fox Adventures leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
Portal placement requires some precision but timing is lenient.
Star Fox Adventures
Lock-on staff combat is deliberately forgiving
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.
Star Fox Adventures
Dinosaurs and bosses are Rare-scripted patterns
Star Fox Adventures leans a little harder on variance, though the gap is small.
Portal 2
Puzzles are deterministic with no randomness.
Star Fox Adventures
Dinosaur Planet is fixed and explorable
Portal 2 leans clearly harder on optimization.
Portal 2
Solving the puzzle's logic IS the entire game.
Star Fox Adventures
Zelda-style dungeon puzzles and item routing are the substance
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.
