They offered old games that worked on modern systems without tinkering. Can't get that on Piratebay. You sure can get dubious "cracks" and viruses though!
Having purchased games from both GOG and Steam, I'd pick GOG over Steam any day. I'd argue that Steam made it more complicated, if only because they force you to install and use a client. And then it forces me to download the game again if I choose to uninstall it from my HD. GOG was a simple download and install, always. I never had to download the game again after uninstalling it, I could just burn it to DVD as is, or move it to another HD.
"This John is an unrepentant lad most likely still in the game. Before anyone criticises SD on technique or outcome, read the caveat he placed at the beginning of the article and get a grip on reality. John is a liar who has not reformed in the least. His comments must be treated with great care and a lot of healthy skepticism."
I've noticed some comments here about how the interview sounded fake, or that it was some sort of scam. I do believe that's because "John" is not being truthful. The interviewer not being a trained journalist probably compounds the problem.
