Suppose, hypothetically speaking, that Valve would decide to stop supporting our beloved game and it would die a quick death. How would you handle it? Would you move on to another online game, ie. cod, GCI or some other worthless piece of excrement and never miss TF2? Would you stop playing games altogether? Maybe you would go into a deep depression and be in mourning for a few days.
I would have a difficult time finding anything that would be able to match this games entertainment value and my time spent gaming would cut by about 80%.
