90% of the time, I would have to say yes, yes they are. I came to the realization of this a very, very long time ago, but going through the recent babblings of system wars has reminded me. Here's a classic example of what i'm talking about: Person A loves Halo, person B dislikes it. Person A insists that Halo is a fantastic game and doesn't understand why person B can't understand this. This discussion will more or less turn into an argument that doesn't come to any kind of mutual agreement. What people should realize before they jump into a heated discussion that deals with the content of video games is that people aren't always going to see your way, sadly the world doesn't revolve around you, but it should, I know, you can complain to me afterwards. Once you realize this you should then come to the conclusion that your personal tastes aren't final, an amazingly crafted game is an amazingly crafted game, no if ands or buts about it. That being said, you don't have to like it. You see, there's an amazing little thing called opinion and everyone has one.
So, all things considered, in a heated argument about video games that deal with whether a game is good or bad, is someone right and someone wrong? I would have to say yes, people should recognize quality when they see it. Sure you may not like it, but remember the world doesn't revolve around you.
