this game hasn't changed since you started playing.
Nope, the game hasn't changed at all except for a few upgrades over the years (which may be a problem in its self), but picture it as you favorite bar. The locals hang out there. You know everybody's name, you are tolerant of even of old "Jimbo" when he drinks too much, but its your place to hang out and have some fun.
Then a big new office building opens up and brings in a bunch of new people. They move into the bar and start playing crap music on the juke box, calling for the TVs to be turned to news programs instead of the sports that are normally there (the news that most people go to the bar to get away from). They order all these wussy drinks and throw money around like its nothing so the regulars can no longer get a waitress to stop by.
The bar is the same, the staff is the same, but the atmosphere is completely different. It is no longer the same bar. So why bother going there any more?
The game has gone the same way and people are leaving.
