One thing is slowly becoming obvious to me: we aren't the market they're selling to.
Consider all the detailed problems and ideas that have come up, things that are shaky if not plain bad. Think of how many times they've been said and, importantly, by whom. "The Fanbase," at least with respect to Isotropic and competitive Dominion, has said he's not paying for what's there already. Most of the strongest critics are also either very good players or very active community members, or both.
Now, these critics would all love to buy an awesome implementation that is satisfactory for truly competitive play. But there's no indication this is forthcoming any time soon, despite our suggestions and thoughts.
The question, then, is: who is the market? Not iOS gamers, who overwhelmingly want an offline implementation. Not casual gamers, who aren't going to pay $12 per expansion pack, and certainly won't buy in bulk to get them cheaper. Not the hardcore players, who want something useful for competitive Dominion. Who, then?
I'll go post that in the Q&A thread, actually.
