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

Optimization · Pure Optimization
A forensic point-and-click about collecting evidence and matching it to scripted suspects.

Optimization · Pure Optimization
LucasArts adventure sending Indy down three routes toward Atlantis.
CSI: Deadly Intent leans Optimization (Pure Optimization); Indiana Jones and the Fate of Atlantis 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.
CSI: Deadly Intent
Pointing and clicking, no twitch demand
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
CSI: Deadly Intent leans a little harder on reads, though the gap is small.
CSI: Deadly Intent
Suspects give scripted responses, not adapting
Indiana Jones and the Fate of Atlantis
No adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
CSI: Deadly Intent
Evidence locations unknown until scenes are searched
Indiana Jones and the Fate of Atlantis
Solutions hidden until reasoned out
Indiana Jones and the Fate of Atlantis leans a little harder on optimization, though the gap is small.
CSI: Deadly Intent
Collecting and matching evidence to suspects solves cases
Indiana Jones and the Fate of Atlantis
Three-path puzzle chains reward deduction
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.
