head to head
Portal 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
The portal-gun puzzle game whose solutions are everything.
Lara Croft Go leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
Lara Croft Go
Turn-based taps, zero dexterity
Portal
Portal placement timing modest.
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
No adversary modeling player.
Lara Croft Go leans a little harder on variance, though the gap is small.
Lara Croft Go
Everything visible on the board
Portal
Deterministic chambers; no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Lara Croft Go
Each level is a solvable movement puzzle
Portal
Pure puzzle-solving optimization.
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.
