Fight a ton of battles, make it to the boss. Beat up the bad dudes, get to the next level. Repeat until you hit the credits. After playing so many games (much to the dismay of our parents and loved ones), we begin to notice some all-too-familiar patterns.

All of our assumptions come crashing down, and everything that we thought we knew turns out to be wrong.

Oh, and if it wasn't obvious, massive spoilers await.
