Your explanation pretty much supports what I said though. If anyone can upload a picture and less people are doing it, then that's a good indicator that the game's dying. Maybe that's not your definition of dying but that's what I define as dying. That doesn't mean that the game will be shut down anytime in the near future at all, but it also doesn't mean that the overall average population hasn't declined greatly.
I don't see why people would be more selfish now than they would before, unless you know, there were just less people playing than before and consequently less people willing to actively update things.
im not denying that there are less players now than there used to be, thats not in question, my point is that wikis aren't a good way to tell if a game is dying or not. there are certainly much better ways of doing that
