I haven't played any of those old FMV games, but I did just watch a play-through of Dracula Unleashed. The Swails scene was the highlight of the whole thing. It would be a buy for me if the whole game was that drunken sailor crying about his buddy Swails. (SPOILER)Here's that there scene if you'd like to see it. It's a bit creepy, so if you don't like creepy things, don't look.
So, have you ever played an FMV game?
