Sandbox Games vs Linear Story Telling Games
As there are many genres of video games, it's usually difficult to compare two different kinds. You can't compare a FPS shooter with the Legend of Zelda series for example. However, these two genres are polar opposites of each other and are often brought up in forums when discussing their own genre. Identify what each genre is, the pros and cons of each one, the limitations of each, and what kind of audience each would appeal to.
