In The Last Express , you yourself are a fascinating, wild, mysterious character. Titanic , in contrast, has a menu-dialogue system. The game provides a list of four or five lines, you pick one, and the other character responds. Traditional, easy to use, and it makes you into a complete nonentity. The original Colossal-Cave featureless protagonist.
People writing menu-dialogue games, take note.
A single scene, late in the game, shows you from third-person perspective. Must be a bit of a jolt for female players. Plot control is a little obtrusive at times. Characters go on convenient errands, leaving thing unattended at just the right time. The interface is quite nice.
