Though I prefer the Xbox version of TF2 much more so than the PC, I can't help but find myself being drawn to the PC now that its free. TF2 PC has long since had things I would kill to have in Xbox. However the stories of hackers, griefers, frustratingly superior players, and now the occasional hilariously bad-playing F2Per keeps me from leaping at the opportunity. Only time will tell, I suppose.
As for Meet the Medic: "Now, most hearts vound'nt be able to vistand such a shock, but I'm fairly sure your heart vill-BLAMO!"
