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

Execution · Practiced Mastery
Simulation driving precision paired with a deep, solvable tuning and setup layer.

Execution · Practiced Mastery
Combo execution and line routing through fixed skateparks for maximum score.
Gran Turismo 5 leans Execution (Practiced Mastery); Tony Hawk's Proving Ground 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 5
Simulation-grade car control and braking precision lead everything
Tony Hawk's Proving Ground
Perfect inputs chain manuals, grinds and Nail-the-Trick combos indefinitely
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 5
AI fields are predictable; online racing stays positional
Tony Hawk's Proving Ground
Multiplayer score battles barely involve predicting opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gran Turismo 5
Tracks and physics are deterministic
Tony Hawk's Proving Ground
Skateparks are fixed and fully learnable
Gran Turismo 5 leans a little harder on optimization, though the gap is small.
Gran Turismo 5
Tuning setups, gear ratios and license-test lines are deeply solvable
Tony Hawk's Proving Ground
Routing the highest-scoring combo line through terrain is the meta
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.
