I bought the Game of the Century Edition of this game and loved it, and just recently I discovered it was replaced without my consent, with an inferior, buggy, third party account required version and also missing content that the original version had. In fact don't buy games on GOG if they are willing to do this to your library. They even went into m y PURCHASE HISTORY and changed the name of the product. GOG has progressively gone downhill and become more corporate garbage with each year since they became popular for offering DRM-free games. Stay away from GOG
They are pulling a bait and switch, DO NOT BUY until they come out and confirm they have added real lossless audio files. People have done analysis of files and the MP3s and FLAC files look identical. Even the editing was 0 effort. None of the tracks fade properly, they either have a determined "end point" followed by silence, or they cut off abruptly and the next track starts immediately. This company has done some really questionable things with the release of the game and their DLC and I would pause before purchasing anything from them again.
