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.

Optimization · Pure Optimization
A story-first adventure with gentle item-puzzle logic as its only test.

Optimization · Pure Optimization
A LucasArts sci-fi adventure where astronauts stranded on an alien world puzzle out its dead civilization.
Back to the Future: The Game leans Optimization (Pure Optimization); The Dig 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.
Back to the Future: The Game
Telltale point-and-click, zero dexterity
The Dig
Point-and-click; no reflex demands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Back to the Future: The Game
Characters follow the episodic script
The Dig
Alien world is static; companions follow scripts.
The Dig leans a little harder on variance, though the gap is small.
Back to the Future: The Game
Puzzle solutions are hidden until found
The Dig
Alien machinery's purpose is hidden until experimented with.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Back to the Future: The Game
Light item-logic puzzles drive each episode
The Dig
Machine puzzles have single fixed solutions to deduce.
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.
