That is the path to certain failure. We made a mistake by focusing primarily on the cRPG community and by ignoring others. We have to learn from that mistake and correct it, not repeat it on a larger scale.
I personally do not agree that taking every opportunity to ensure your reputation is upheld is the path to certain failure

Anyway, I agree that basing solely on crpg community will not ensure the success of M:BG, and definitely the marketing will be needed before any form of sale, whatever the form of it you adopt. Kickstarter campaign showed that very clearly.
But I also think that at the moment, at least, the crpg community is the biggest population willing to support/buy the new game: do something
pro publico bono to make it happen, buy the game when it is released, participate in Alpha and Beta - you name it. So please do not make the mistake of focusing primarily on others and ignoring the cRPG community...
