head to head
Sam & Max: Hit the Road asks more than Riven: The Sequel to Myst, and the gap is variance.

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

Optimization · Pure Optimization
An absurdist road-trip puzzle game testing comfort with wildly lateral inventory logic.
Riven: The Sequel to Myst leans Optimization (Pure Optimization); Sam & Max: Hit the Road leans Optimization (Pure Optimization).
Sam & Max: Hit the Road leans a little harder on execution, though the gap is small.
Riven: The Sequel to Myst
no reflex or physical skill required
Sam & Max: Hit the Road
Cursor-driven; no reflexes tested at any point
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
Sam & Max: Hit the Road
Episodic comedy adventure with no adaptive opponent
Sam & Max: Hit the Road leans clearly harder on variance.
Riven: The Sequel to Myst
fully deterministic puzzle world
Sam & Max: Hit the Road
Carnival mini-games add slight randomness but are trivial
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
Sam & Max: Hit the Road
Absurdist puzzle chains are fully solvable with lateral thinking
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.
