The movie vs the game?

[Jeava]

Ok so I know this has been asked like a thousand times. so if anyone would be willing to offer a link or hint to where to find out I'd appreciate it, but it really has been bugging me ever since I started playing PotC. How (if at all) does the game fit into the movie storyline? I'm not giving any spoilers here, but not one of the main characters in the game (with the possible exception of Swan) is where they were at the end of the movies.. just curious about this. lol
