Dark, I'm on it. 

@Danny I'll be very glad if your game comes about, and I do understand very well the issues with all aspects of producing a game, it's just that what mildly frustrates me in this respect is that all the necessary tools are there. Castaways and Lunimals showed how to do real time development and management of free acting units, Time of Conflict had the awsome map interface, and anyone with a skill in writing descriptions could design a colourful world for the game. All the elements are there, but nobody has put them together quite yet, which, given that we now have several audio games in genres from fps, to vehicle sim to some pretty good in roads into rpgs is really quite surprising, and a little frustrating considering that most of what is! accessible is of such an amazingly inferior click click minimax quality.

Kodp and Castaways are very much exceptions of course, though neither is really up to the dwarf fortress level sinse Kodp, while amazing in many ways isn't just! a civilization and settling game and castaways doesn't quite go far enough, ---- though if Aprone plans a castaways ii, or something similar I'm all for that.

I suppose it was just reading Martin's fantastic history of Westeros it struck me this would be an amazing thing to get stuck into, to take a group, rather like the Andals colonizing westeros, in a hostile environment where you could find literally anything, guide them to overcome weather and hostile natives, to explore for teretory and resources and then see them build an ever more complex civilization going from a few crude huts in the forest to fully fortified castles and entire cities, building their own ships and sending out new colonies of their own.

It's actually a little odd, back before I played castaways I knew people who enjoyed that style of game but could never see the appeal, sinse the only examples I'd had access to had been the boring, numeric multiplayer variety. Castaways however with it's disasters and it's need to continually keep a handle on the environment and what was happening, and change your stratogy and priorities so that you could react to threats really! showed me what was possible, and now it's something I can't wait to try.

For the same reason we don't have any proper games in a dozen other categories: only a handful of people are interested, and only a small subset of that handful is capable of doing the development. Sighted devs are nowhere near post-scarcity in terms of market, human resources, or funding, but compared to accessible game devs, they might as well be. The average indie dev can hop on to kickstarter, make a campaign with perks and a video, and call up half a dozen friends, and 30 days later they have all the necessary funding, and if they can't program that well, they always have Unity3D.
Crowdfunding something so niche, especially when this depends on the accessibility of the crowdfunding sites and/or getting sighted devs to take the risk, is hard enough that we're already down to what can be built for free or devs who can handle the financial obstacle. We don't have robust, easy-to-use engines to speed things along. We don't have an audience even 1% that of graphical games.

Solutions come down to some combination of these traits, according to the whole thirty seconds of thought I just put into it:
Conscientiousness, Charisma, and/or a big pile of money. (This would have been easier in Japanese! や'ya' would be the perfect conjunction, here, but English doesn't really have it.)
And, even better, if you have one of the three, you can probably magic up a little of the other two. They're all rather versatile.
Hardly anyone here has the money, so it's a question of how much of the other two are floating around.

Oops, a rant. That's not what you ordered :-/

I've watched a few sighted friends playing civilization, and I loved the game.  I was very excited when Castaways came out, and I think I played that game for hours and hours.  I'd love to see more like that.

There's also no open world games in the audiogame community that I know of, except for maybe Swamp.

I love the concept of open world where you just go around doing what you want, yeah mudding can be open world I suppose, but I'm not really into muds, too many commands to memorise and not all of them have soundpacks.

Let's face it, a mud with no soundpack is rather boring.

Is there such a thing as an audio MOO?

I'm thinking of concepts like some of the popular muds, but turn them into audiogames, if that is even possible.

Quite a lot of work I'm sure, but it would sure be worth it.
