head to head
Live for Speed asks more than Grid 2, and the gap is execution.

Execution · Practiced Mastery
Cornering execution over memorisable circuits, with light prediction in wheel-to-wheel multiplayer.

Execution · Pure Mechanics
A long-running hardcore racing simulator prized for its tire physics and online racing.
Grid 2 leans Execution (Practiced Mastery); Live for Speed leans Execution (Pure Mechanics).
Live for Speed leans clearly harder on execution.
Grid 2
Car control through corners is the entire moment-to-moment test
Live for Speed
Hardcore sim handling rewards perfect car control
Live for Speed leans a little harder on reads, though the gap is small.
Grid 2
Online wheel-to-wheel adds light positional prediction
Live for Speed
Online racecraft against human rivals
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grid 2
Tracks are fixed and fully visible
Live for Speed
Deterministic physics, no weather lottery
Live for Speed leans a little harder on optimization, though the gap is small.
Grid 2
Racing lines, braking points and car selection are studyable
Live for Speed
Setups and racing lines converge to known optima
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.
