For what it's worth, the Wiki seems to be a bit strict about what can or can't be added. A fangame has to have at least the Prologue and first chapter (Daily Life, Deadly Life, Trial AND Execution) be officially released before the game can be added, and the second chapter has to be officially released before individual articles for that game can be made. Plus, it has to be either a game or some kind of video series: no literature or the like. It could just be that there aren't that many games that reach those demands yet, and even if they do, there's no guarantee it'll be added. There seems to be a lot going on with that Wiki...
