This topic is ridiculous. You can't separate the journey from the destination, the punchline would have been nothing without the buildup. You know, telling a story is like treating a foot fungus, you can have your socks, and you can have your clotrimazole cream, but only together do they make a foot fungus treatment. Apart, all the socks will do is make your feet get all hot and sweaty and make the burning even worse, and the clotimazole cream will just rub off on your carpet.
In the same way, Mass Effect 3's ending wouldn't have been nearly as great without the beginning and the middle. It is only the fact that BioWare got the fanbase so emotionally invested in saving the galaxy from the reapers over the first 119 hours and 50 minutes of the trilogy that made the last 10 minutes so hilarious, in which Shepard is for all intents and purposes defeated by the reapers' creator and forced to do their job for them. The Mass Effect Trilogy might be the most elaborate shaggy dog story in popular culture, and too many gamers fail to appreciate how great that makes it. It may have taken me almost two years to get the joke, but when I finally got it I laughed my head off. Good one, BioWare! Can't wait to see how they top this in ME4.
