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

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

Optimization · Pure Optimization
The Myst sequel: a slow, wordless puzzle adventure solved by observing an alien world's internal logic.
Indiana Jones and the Fate of Atlantis leans Optimization (Pure Optimization); Riven leans Optimization (Pure Optimization).
Indiana Jones and the Fate of Atlantis leans a little harder on execution, though the gap is small.
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
Riven
Point-and-click; no dexterity required at all
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
Riven
No opponent of any kind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Indiana Jones and the Fate of Atlantis
Solutions hidden until reasoned out
Riven
Information is hidden only until you observe it
Riven leans a little harder on optimization, though the gap is small.
Indiana Jones and the Fate of Atlantis
Three-path puzzle chains reward deduction
Riven
Deciphering the world's logic is one giant solvable puzzle
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.
