Here's my take on this 'storyteller' business.
#1 - the official story is finished. Rarebit has posted everything he had written, therefore there is no need to act out what wasn't implemented in-game. Why would you want to continue something you already know how it goes?
#2 - the idea of the official Matrix story being written by a player is not a good idea; it would end up a fastidious, exclusive mess. Players can write stories that are generally upheld by a majority of players, but that don't make it canon, nosirree. Rarebit had his vision of the Matrix story. Paul had his. Phrack has his. Deimos has yet another. ALL of those visions are just "so-and-so presents:the Matrix". The only thing that will ever be truly considered canon is what comes out of the Wachowski's direction in the various media that their version of the Matrix story has been told.
#3 - the story of the Matrix has nothing to do with war, or peace, or control. The Matrix itself is just a setting for the story. The real story of the Matrix was about the people; Neo, Trinity, Morpheus, the Oracle, the Merv. It wasn't about fighting for freedom, or maintaining control, the story was about how the people reacted to the situation they were faced with. The war and the Real and the Matrix, those are all just backdrops for the drama between these people. No successful story has ever been written about the scenery.
#4 - it has been proved over the last year that the war is unsustainable in this media. People can't really die, bombs can't really explode, the setting can't really change. What are you going to do the first time a player decides to grief the RP by reconstructing after their "jack has been pulled"? Nothing except whine about this being why we can't have nice things. A truce between the orgs is the only viable, playable situation for this MMO.
#5 - speaking of things not really changing, there is no way to make the kinds of changes in-game that have been described here, without making the game open-source. For example, "reduced to rubble" is a phrase I saw thrown out there; and how would you go about doing that? Is there a structure, or textures, in-game that exists for a bombed-out Metacortex building? Or Sobra Shores Church? Do rubble structures or textures exist that would be convincing enough for story immersion? I think the problem here is that not enough people understand how these game mechanics work. They also don't credit the devs with having already thought of and discarding this as not possible. New coding would have to be added, which means open-source, which means forget it jack, cause it ain't gonna happen. There is no way in hell the Matrix franchise will ever be open-source.
#6 - there is also no way they will ever give control of the likenesses of the main actors from the movies away to players. Or dev tools such as NPC quest givers and meatwad abilities. There's just too much risk of abuse.
On the other hand, in the absence of an official storyline, well. . .beggars can't be choosers. So, if it turns out that Rarebit is not being replaced, or his replacement assumes more of a "caretaker" role, then I think all bets are off.
Maybe a forum could be set-up where everyone is anonymous and anyone can have access to develop the story. The story can be developed and implemented using what meager tools we have, and a great deal of suspension of disbelief will have to transpire. That would be better than nothing, I suppose.
But I gotta tell ya, I really despise those who would seek more fame through this...opportunity...crisis...or whatever you want to call it. If you're not willing to step aside and let others do it, and help and encourage them in their pursuit, you're not the right man for the job.
