Titanic was my very first adventure game! My brother gave it to me when he gave up on it. Who knew it would start me down the path to BAAGS?
I love this game, and as far as I remember (I replayed it several times), the only timed sequence came at the very end, when, as Jenny said, it is one big long timed sequence. And there are a few slightly different endings, but only one good one! well, good, except for the fact that the ship still sinks, of course.
