I just popped over to one of the torrent sites to see if they would actually have Doom3 up there, and sure enough they did. I have no intention of d/l'ing D3 and plan to buy it, but I was just curious to see what type of traffic it had.
There were numerous torrents up, two of which had nearly 30,000 people downloading it and another with over 4000! Come on! That's just stupid! That's just something I have never seen. I can't see how any of them are actually getting anything either. As a rule I tend to stay away from anything that has over ten times as many leechers as seeds, and several of them were well beyond a 10:1 ratio.
Buy the game people and save yourself the embedded virus!
