People have already used it as a reference on here before, this is a wiki, aka public knowledge is public knowledge. It's not like anything on that guide isn't from the exact same game or anything. Oh wait.

In all seriousness as long as nobody does a lazy job and just copy-paste from that article it's fine. It can be listed as a cited source as long as you are not directly stealing the author's writing.
