It does not need to be a physical medium, but an external source nevertheless, preferably one that is well-known and reputable enough to qualify as a source. For example, if a major gaming website, preferably several, would write a piece on FH2, then it would be quite OK by Wikipedia's policy to create a page. In the absence of such articles and references to them, however, any FH2 page is self-promotion (banned) or original research (banned). Lately, they have also taken the stance that the pages should be of "general interest", which is IMHO quite artificial limitation and almost sounds like a weasel word by itself. ("Some would argue, that this page is not of general interest.")
