Backgrounds are magnificently and authentically reproduced from pictures and the actual ruins. The character models, too, are well drawn and are very realistic. The sound is nothing short of magnificent. Perhaps even more so than the graphics, it succeeds in pulling you back through the centuries to the time when Pompeii was at its prime. The classical strains are a joy to hear, and they set the mood for the game marvelously.
Sound effects are adequate.
The voiceovers are my only sound-related problem. First of all, there is no attempt at lip-synch whatsoever. The characters stay still while the words are spoken. In another game this would be a disaster, in Timescape however, there is so much atmosphere packed in, that at first you hardly notice this. Less seriously, the accents are not at all authentic.
