head to head
Grim Fandango asks more than Riven: The Sequel to Myst, and the gap is variance.

Optimization · Pure Optimization
A noir puzzle journey through the Land of the Dead solved by untangling the game's own surreal logic.

Optimization · Pure Optimization
A cerebral puzzle-adventure that is essentially a logic puzzle to be fully solved.
Grim Fandango leans Optimization (Pure Optimization); Riven: The Sequel to Myst leans Optimization (Pure Optimization).
Grim Fandango leans a little harder on execution, though the gap is small.
Grim Fandango
Tank controls are awkward but never a skill test
Riven: The Sequel to Myst
no reflex or physical skill required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grim Fandango
All characters follow scripted arcs; nothing adapts to the player
Riven: The Sequel to Myst
no opponent present in the game
Grim Fandango leans clearly harder on variance.
Grim Fandango
A few timed sequences add minor uncertainty but nothing critical
Riven: The Sequel to Myst
fully deterministic puzzle world
Riven: The Sequel to Myst leans a little harder on optimization, though the gap is small.
Grim Fandango
Surreal multi-act puzzle chains demand patient causal reasoning
Riven: The Sequel to Myst
pure logic-puzzle solving, walkthrough-solvable
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.
