Lost: Via Domus, has a lot going for it, there is a great storyline and challenging quests/missions.
If you have watched any of Lost as a TV i think this a really good game, as long as you have watched the show. The main storyline of the show, puts you (a made up character) into the positions of the other characters, if you do have a little background knowledge of the series this will help you some-what with the game, but not massively. There are only a handful of missions/quests to complete but there are little bits during the story like that keeps you interested like, you've got to take a correct photo, by looking at a torn up photo.
There are some disappointments with the game, such as the short storyline, and also the characters. Some of the characters voices sounded nothing like them off the show.
