ups to model textures as well as further photos of additional features such as doors and signage, leading to up to 20 reference photos per building. 3D artist Mark Sharratt, the lead on the San Francisco map, told Official Dreamcast Magazine that he "start by scanning in the District Council Land Use contour maps and bringing them into Softimage, then drawing round them to get the scale right", before using the reference photos and video "to get everything the right shape". Sharratt said he then "scan[ned] in all the photographs, remove the perspective in PhotoShop to make them straight", before "remov[ing] the people, trees, wires and stuff from the pictures so they can be used as textures for the buildings". This process was repeated for each city of around 1.5 square miles. The first PAL release had a number of major bugs. Unsold discs were quickly recalled and replaced with a second PAL version that eliminated most of the major bugs, but not all. Sega Europe also offered replacement disks, the final PAL version, free of charge to anyone who had purchased a bugged copy. The US release and the final PAL version were both free of major bugs, although some minor ones remained. Martyn Chudley stated that although Bizarre Creations had fixed all bugs reported to them by Sega (who were in charge of Quality Assurance) before release, some bugs must have slipped through Sega's comprehensive testing plan due to the sheer size of the game. Metropolis Street Racer was also the first racer to have radio stations and DJs talking between music tracks. The soundtrack was composed by Richard Jacques. Some songs in the radio stations are sung by TJ Davis, who also sung songs from the Sega Saturn game, Sonic R. Reception The game received "generally favourable reviews" according to the review aggregation website Metacritic. Jim Preston of NextGen said of the game, "Full of good ideas, great graphics, and expert driving, this one hits on all cylinders." Brandon Justice of IGN said that it "has a great sense of progression, difficulty and refinement throughout, and while it may be too difficult for people with little patience, it is one of the most rewarding gameplay experiences in the history of the genre." However, Shane Satterfield of GameSpot called it "a beautiful racer with accurate physics and tight control, but the kudos system makes it far more challenging
