Driving Strikers - Dreamcast (signed)

Driving Strikers is an overhead 4 player soccer-type game where the cars are the players. 

Voiced by John Riggs (literally me)

Though this is the UK version, all discs are universal so they on US, UK, and Japanese Dreamcast systems.

Here's the offical description:

The automotive football game you never knew you needed... Forget the licensed cars and sponsored wraps, Driving Strikers is arcade-perfect full 3D extreme sports action! 

Featuring online play compatible with Modem or Broadband Adapter.

Take on players worldwide and rock out to a nostalgia-inducing soundtrack of 2000s bangers!
