head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
LucasArts adventure sending Indy down three routes toward Atlantis.

Optimization · Pure Optimization
A Myst-successor puzzle adventure about decoding alien machinery across spliced worlds.
Indiana Jones and the Fate of Atlantis leans Optimization (Pure Optimization); Obduction 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.
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
Obduction
Walking and clicking only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Indiana Jones and the Fate of Atlantis
No adaptive opposition
Obduction
No opponents at all
Indiana Jones and the Fate of Atlantis leans a little harder on variance, though the gap is small.
Indiana Jones and the Fate of Atlantis
Solutions hidden until reasoned out
Obduction
Deterministic alien machinery
Indiana Jones and the Fate of Atlantis leans a little harder on optimization, though the gap is small.
Indiana Jones and the Fate of Atlantis
Three-path puzzle chains reward deduction
Obduction
Number-system and swap-machine puzzles are fully solvable
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.
