I guess I still don't understand why it's so important to you that you "count" digital games or don't count them. Since you can't sell them and you don't need additional physical space to store them and they have no actual resale value and you don't need to keep them clean or maintained or really do anything but play them, what does it matter if you have five or a million of them? Those games are part of your library, but I can't see how they could be considered a "collection" any more than browser versions of arcade games would be counted in your arcade collection or MP3s of vinyl albums would be counted in your record collection. Yes, it shares the basic media elements of a video game and it can generate that enjoyment experience, but I just don't think most people would agree that you can have a collection of items which can't be sold or handled in some physical way.
