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.

A hidden-object adventure about solving fixed puzzles to follow a Norse mystery.

Optimization · Pure Optimization
LucasArts adventure sending Indy down three routes toward Atlantis.
Endless Fables 2: Frozen Path 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.
Endless Fables 2: Frozen Path
Point-and-click and hidden-object hunting, no dexterity
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Solving inventory puzzles and finding objects is the loop
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.
