head to head
NCAA College Football 2K3 asks more than Grid 2, and the gap is optimization.

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

Optimization · Practiced Mastery
A college football sim about playbooks and rosters.
Grid 2 leans Execution (Practiced Mastery); NCAA College Football 2K3 leans Optimization (Practiced Mastery).
Grid 2 leans a little harder on execution, though the gap is small.
Grid 2
Car control through corners is the entire moment-to-moment test
NCAA College Football 2K3
snap timing and throwing precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grid 2
Online wheel-to-wheel adds light positional prediction
NCAA College Football 2K3
scripted CPU defense, not adaptive
NCAA College Football 2K3 leans a little harder on variance, though the gap is small.
Grid 2
Tracks are fixed and fully visible
NCAA College Football 2K3
fumbles and bounce randomness
NCAA College Football 2K3 leans clearly harder on optimization.
Grid 2
Racing lines, braking points and car selection are studyable
NCAA College Football 2K3
playbook and roster management
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.
