These are but a few moments the make gaming worth it. The haters, the corporate bullshit, it's all meaningless when something truly memorable happens. We may complain and we may argue and we may feel betrayed and we wonder if it's all worth it. But in the end, we're all on the same team and we all got in this for the same reason. To conquer, to explore, to triumph.
