As do I on occasion however it only works for so long without changes before you see the player base become drastically reduced out of sheer boredom. It's an issue of replayability. Let's imagine CN was a single player game for a moment with all others being AI. Speed the time up so that 3 years passes more quickly. What would keep you returning and wanting to play a new game after the third, fourth, fifth, sixth, etc. time?
I have a great distaste for that sort of idea. It adds little to nothing new from a depth perspective and the lacking of depth in the game itself could be mentioned as a reason for the lack of interest. This isn't to say it needs to be rocket science. Some new functions or say reworking what already exists could have a profound impact on player interest while keeping the history the game presently has.
