Project Gotham Racing

For thoughtful child sponsors
Project Gotham Racing (PGR) was a launch title for Microsofts' Games Console and swiftly became the second best selling game for the Xbox after .

PGR differs from most racing games in that winning a race doesn't mean the player advances to the next round, instead advancement in PGR was down to a combination of being fast enough to meet the challenge set, and scoring enough Kudos points to advance.Kudos points are gained through the player's driving skills, such as power sliding around a corner at speed, or overtaking other NPCs in the race.

A sequel to this game, called Project Gotham Racing 2, was released in 2004.
