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 · Systems & Chaos
A ghost-noir adventure testing clue association and patient investigation.
Back to the Future: The Game leans Optimization (Pure Optimization); The Blackwell Convergence leans Optimization (Systems & Chaos).
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 Blackwell Convergence
Pointing and clicking has no dexterity test
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 Blackwell Convergence
Characters are scripted dialogue trees
The Blackwell Convergence leans a little harder on variance, though the gap is small.
Back to the Future: The Game
Puzzle solutions are hidden until found
The Blackwell Convergence
The mystery's facts are hidden until uncovered
Back to the Future: The Game leans a little harder on optimization, though the gap is small.
Back to the Future: The Game
Light item-logic puzzles drive each episode
The Blackwell Convergence
Connecting clues and notebook entries is the core 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.
