We have been exploring options for allowing people to participate financially post-Kickstarter. I don't think anything like the sort of "escrow account" that was suggested earlier in this thread has come up, and I'm not going to make any official announcements in this thread, but we do have some ideas on this, and we intend to give as much real value for any such contributions as possible.
Depending on just how well the "add ons" for swag sell, we are likely to be working to open a swag store as one such means. No promises (I have not been connected to that side of things lately, so I don't know with the certainty that I would want before making any such promises just how far along that is; last I heard, we expected the transition from "meeting swag distribution requirements for KS" to "open online store" to be more than feasible), but it is quite likely, as it will be a sort-of low-hanging-fruit that does give real value for backing. If you're interested in any of the swag on the KS, please do buy it through backing us there. Not only will that likely be delivered before we get a store up and running (and, if not, it'll be the first things we deliver after doing so), but each new backer increases our "backers" count, so if you're not already backing us but want swag, please buy it that way. More backers translates to a stronger position for our business department when they go to do their job: it proves we have the customer base to truly make this profitable. (What we have already - and what we're immensely thankful for - is proof that our audience is devoted. And that, too, is powerful leverage. But it's a slam dunk if we can prove that it is also very large, because a large base can sustain what can only happen in bursts from a devoted one. And steady stability is the holy grail of the kind of business with which WE want to do business. The kind that will help this be a long-term endeavor that serves its customers for many many years.)
We absolutely intend for there to be means for players to continue playing the game in the event of and after a shut-down. Not that we have any intention of shutting down if it keeps supporting itself! But should it happen for any reason beyond our control, we fully intend for players to be able to keep playing, with or without MWM. The exact method for that is not set in stone, but the rough idea is as discussed on the radio show. It would take something truly monumental for the game to go live and then be shut down in a way that the players could not continue using what had already been produced.
If you want more details that are a little firmer, I recommend finding a recording of the radio interview.
You guys are awesome, and if I seem a bit rambling, it's just because I can't express my awe and gratitude to see this community still going strong like this, and am a bit overwhelmed and humbled by the support this effort is getting. Good work, everybody!
