Extra Credits talks about the "exposition dump." What is that, you ask? The "exposition dump" is one of the easiest ways with which a developer can tell a story, explain a game world or explain a game world's rules. Even lauded game designers like Hideo Kojima use this method to tell a story—and why not, if Metal Gear Solid's success is any indication, there are few repercussions for overusing it. Thankfully, there are examples of doing the opposite and being rewarded for it. The Half-Life series, Fallout 3 and Journey are examples of doing it right.
