Over on the ihobo blog today you'll find this piece constructing an argument that a videogame has never made you cry. Here's an extract:
...a story can make you cry by empathising with the protagonist (or another character), but a game (when viewed as a formal system) cannot do this. It follows that the only way that a videogame can make you cry is by using narrative tools that have nothing to do with games as formal systems whatsoever. So even though, for instance, many people report that they cried when they played Final Fantasy VII at the fateful scene (and indeed, several other cRPGs also show up in player studies as having provoked tears) the moment that actually brought the player to tears was a non-interactive cut scene. It wasn't the game (in the systems view) that made them cry – it was the story – and there never was a question as to whether stories could make you cry.
