I agree with Anabstercorian's views. This is a war. This is beyond a game. Our characters, our nations, our dreams for the IR have experienced life...
It is now time to face death.
We have seen, so many wierd things these 7 long turns... twists of fate, sudden surprise alliances, nuclear explosions, usage of 11th level magic... to stop now, to say that it all works out fine in the end, when we damn well know that it isn't and won't end up that way without a whole lot of effort, would be lying to ourselves.
I say, go on. We as people, our characters, and everything that we have interacted with has grown and evolved throughout the last four months. It is as though the world in which we have gamed is alive. To simply stop, is to destroy that suspension of disbelief. To stop, and say that everything would work out fine, would be to destroy everything that we have worked for.
To go on, is to suffer the same fate. But... it would not leave any of us with a feeling of regret... the ocassional thought of: "What would have happened?"... I, for one, could not go through the next few weeks, months, or possibly even years, without wondering what would have happened... everything has it's ups and downs, and I think that we are about to enter the lowest point, from our perspective, the IR has ever hit... it will be nasty... but even so, it will be fun. And the world will still feel... alive.
And, IMHO, the world feeling alive is more important than having fun... we have had a lot of fun thus far, it is time for the realism of the world of the IR to set in, for us to truly feel the profound effects of our actions and suffer the consequences... let us understand what we have done to the world, to the universe, and make the realism come forth in all it's bloody and destructive splendor...
