I was lurking in the gb forums and saw some random topic about boss battles. I started to think about some of the awesome boss battles I've done, which then lead to the realization that boss battles are either not in most games or are insignificant. Think about it - where are all the memorable ones? Even if boss battles still exist in most games, they aren't as much a part of games as they used to be. When's the last time you beat a game when your friend beat it and you and they we're all like "Dude, Dark Matter was sooo epic, especially with the whole space setting and you get to fight him WITH Gooey!!! OMG!"  
 
I miss that...
