head to head
Portal 2 asks more than Lara Croft Go, and the gap is execution.

Optimization · Pure Optimization
Turn-based board-puzzle distillation of Tomb Raider's traps and tombs.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Lara Croft Go leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
Lara Croft Go
Turn-based taps, zero dexterity
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.
Lara Croft Go
Hazards move on fixed rules
Portal 2
No opponent; puzzles are static.
Lara Croft Go leans a little harder on variance, though the gap is small.
Lara Croft Go
Everything visible on the board
Portal 2
Puzzles are deterministic with no randomness.
Portal 2 leans a little harder on optimization, though the gap is small.
Lara Croft Go
Each level is a solvable movement puzzle
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.
