...Because there's in fact more to it, as Hechelion pointed out, and often people ask specifically about their games being quarantined.
Sorry, didn’t notice the post above. Everything makes sence now. Thanks.
Still, adding some kind of glossary of frequently used terms and their explanation to the FAQ page, or somewhere else would make things easier in the future. As I said, I would have never known what the difference between de-listed and quarantined is if I didn’t ask.
