Yes, it does. You're not paying the people who made the damned game for the pirated copy you are using. Your money is going to a nerd-jackass that is making money off of a product that isn't his. It's illegal, and more importantly, it's detrimental to the video game industry as a whole. You're not being an "anarchist" or "political activist" by stealing your video games. You're being a cheap asshole. That's all there is to it.
