@Blue Ink: With achievements, they've convinced people that having lots of them is a good thing. In reality, you are meat to be sold to the companies that make games for a cut of the profits.
This is starting to remind me of the kinds of people who always find a way to bring up how their team won the regional <insert random sport> championship in high school. It's meaningless! Stats are meaningless unless they are tied to something real. Video games, by definition, aren't real. YouTube views aren't real. Social network friends aren't real.
However, I have no right to tell you that you shouldn't do all of that. We all should be able to do whatever makes us happy as long as it doesn't hurt somebody else. Just stop acting surprised that the rest of us aren't impressed.
