I realize this the last post to this thread was months ago, but I wanted to chime in because I just finished playing the Wii version of this game last night. It is similar to Adventure Out of Time, but it's more like a set of logic games and puzzles that just happens to be set on the Titanic. There's very little moving animation; most of it is animated stills with voice-overs. And you can't move freely about the ship, which is a bummer because it would have been really cool to see it with modern game graphics. You move around by clicking on areas of a map.
It's a neat little diversion and not too difficult if you don't mind thinking a little bit. I think, though, that Adventure Out of Time is the better video game. The plot was so much more exciting!
