The latest one was the Last Specter, which just came out Monday :P I think you're thinking of the Elysian Box, which is the box from the second game: the Diabolical Box (it's called Pandora's Box in some areas). If that made you cry, Unwound Future's ending will literally break your heart into pieces and then spit in your face with emotion.
I'm definitely more of a story person too! I do plan on going through the games and solving all the puzzles just to get 100% completion but the main reason I play it is for the plot, even if every game has the same basic story features.
