Lots of video game makers want to incorporate puzzles into their games. They give you time to relax your fingers and stretch your brain. Sure, they don't always make sense, but hey, these are video games, right? They're allowed to break from reality now and again. However, certain puzzles are... far more common than others. How many times have you seen a door flanked by two switches and a block? How about a door that will only open if you complete an arbitrary tile-flipping puzzle? Probably a million times, right? These are the Stock Video Game Puzzles. Almost every adventure game in existence uses at least one of them somewhere.
