The thing is, not every game has a large community, which should be the first priority.
Last time I wrote something was on November 14, but that doesn't mean I'm never active, I visit this forum atleast once a day, but I barely find something interesting to share with people or write something in another topic.
THIS might be another big issue, if people can't share experiences about the game, making topics and/or commenting on somebody else's, there's not a lot we can do to keep it alive, especially if admins give up too.
We know pretty much everything about Bully after 10 years.
I only have faith in modding, believing that maybe, someday, projects like Bully: MP could be released, or map editing could become possible, these are things that could revive the community. (I might be wrong, maybe there are still interesting secrets like easter eggs to find that will attract people, "Easter egg found 10 years after the game's release" but I doubt it)
However, I also find it a bad move for the admins to abandon the forum during this period, it's been a long time since I saw more than 100 users/guests connected at once.
Worst thing is that we can't change avatars or ultimate profiles.
