head to head
Portal asks more than LEGO Indiana Jones: The Original Adventures, and the gap is optimization.

Optimization · Pure Optimization
LEGO romp through the original Indy trilogy's set pieces and puzzles.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
LEGO Indiana Jones: The Original Adventures leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
LEGO Indiana Jones: The Original Adventures
Whip swings and brawls, very forgiving
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.
LEGO Indiana Jones: The Original Adventures
Scripted foes and traps
Portal
No adversary modeling player.
LEGO Indiana Jones: The Original Adventures leans a little harder on variance, though the gap is small.
LEGO Indiana Jones: The Original Adventures
Everything placed deterministically
Portal
Deterministic chambers; no randomness.
Portal leans clearly harder on optimization.
LEGO Indiana Jones: The Original Adventures
Item and character gating across replayable levels
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.
