When I was a kid, you were in one of two camps: Nintendo or Sega. You'd talk with your friends about which was superior and why. Of course, the real reason that you were on either side is because that's the console that you had at home. When you played with your friends, you just hooked up another controller, and everyone had a good time. But now when you choose a side in the console wars, you're generally prevented from playing with anyone that doesn't play on the same device. This is slowly changing, however.
