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
A cerebral puzzle-adventure that is essentially a logic puzzle to be fully solved.

Optimization · Pure Optimization
A dual-world adventure solved by mapping inventory logic across fantasy and science fiction settings.
Riven: The Sequel to Myst leans Optimization (Pure Optimization); The Longest Journey leans Optimization (Pure Optimization).
The Longest Journey leans a little harder on execution, though the gap is small.
Riven: The Sequel to Myst
no reflex or physical skill required
The Longest Journey
Pure point-and-click with no time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Riven: The Sequel to Myst
no opponent present in the game
The Longest Journey
Scripted fantasy narrative across two worlds
The Longest Journey leans a little harder on variance, though the gap is small.
Riven: The Sequel to Myst
fully deterministic puzzle world
The Longest Journey
Linear world states with essentially no hidden randomness
Riven: The Sequel to Myst leans a little harder on optimization, though the gap is small.
Riven: The Sequel to Myst
pure logic-puzzle solving, walkthrough-solvable
The Longest Journey
Inventory puzzles require systematic lateral thinking across two realms
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.
