You, me, and @ballz put in several hundred hours of Left 4 Dead. My count was 400 for the first game, and only 100 for the second game. Those were the days! My computer can't even handle Left 4 Dead anymore.
I don't play shit anymore. This is unfortunately the reason why I'm not actively developing the Trash Epics game, because while it seems like a good coding endeavor, it's entirely overwhelming, and I have no good ideas, nor the patience for it.
