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 continuation puzzle journey where mechanical and environmental obstacles yield to patient reasoning.
Indiana Jones and the Fate of Atlantis leans Optimization (Pure Optimization); Syberia 2 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
Syberia 2
Interface unchanged; no motor skill tested
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
Syberia 2
Continuation of scripted narrative with fixed characters
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
Syberia 2
Deterministic world state throughout
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
Syberia 2
Environmental and mechanical puzzles reward patient logical mapping
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.
