This site looks kinda weird. For one, it looks much more polished than any similar site I’ve seen so far. They have really good SEO as well, always popping up pretty high on Google. They have a massive selection of content.
How can they still be up?
What’s the catch/what’s wrong with them?
IGG /nosteam uploads presumably means that they are the sources of the games. I don’t know a huge amount about game piracy, but it sounds like IGG / nosteam are not trustworthy.
