The Greek and Portuguese edition came with the same discs as the British/ European and Nordic editions.
Copies sold in Portugal came with three stickers on the back. One sticker states it was distributed in Portugal by Ecofilmes, one has an Ecofilmes barcode covering the original barcode, and the last is an IGAC M/16 age ratings sticker. The IGAC sticker is dated 1999, so they were not put on the games from the start.
