head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
An encyclopedic driving simulator spanning 700 cars and decades of automotive history.

Execution · Practiced Mastery
Polished pool simulation testing cue precision and multi-shot positional planning.
Gran Turismo 4 leans Execution (Practiced Mastery); Pure Pool leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 4
Hundreds of cars all demand precise inputs
Pure Pool
Stroke precision and cue control decide every frame
Pure Pool leans a little harder on reads, though the gap is small.
Gran Turismo 4
Fixed-line AI offers no adaptive opposition
Pure Pool
Online opponents allow minor safety mindgames only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 4
Deterministic outside slight tyre wear modelling
Pure Pool
Open table, deterministic physics, nothing hidden
Gran Turismo 4 leans a little harder on optimization, though the gap is small.
Gran Turismo 4
Event-by-event car and tune selection is deeply solvable
Pure Pool
Pattern play and positional theory are deeply learnable
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.
