When a game is dead

I was reading this thread on RPG.net on Ars Magica and I think it perfectly sumarizes for me when its time to move on from a game. When yu realize that different people are saying the same things (with no variety) that were said 10 years ago. Including things you yourself said and have moved on. When the core fans can't think of anything new and creative to do with the game, then its time for me to move on.

Of course I'm currently butchering up a definitive dead game, so take this statement as you will.
