The fact that it doesn't (get deleted) now is an obvious sign this game has reached its zenith, or apex in users. That usually means it's time to focus on getting as much out of it as possible for the devs. They start to invest less and less effort, as it's already past its prime. They'll be focussing more on new projects as this game ain't likely going to get better then it is now. (for its stakeholders)
I wish I would have found this game sooner, assuming it once was better? Perhaps the veteran managers here can answer that. Has this negativity always been here, or is it sth quite recent? I think the concept is briliant, if tactics and so on would really work. It's a great format to start from.
