So, one day, I was talking to another IRL dominion enthusiast who does not visit these forums, and I was talking about the reasons for the half expansions, specufically the greman publishers wanting a small expansion. What ended up coming out of that discussion was a very simple design idea for continuing dominion.
The concept is this: pre-packaged kingdoms. All donald would have to do is design ten cards at a time, package them with a little booklet equivalent to the card descriptions section of the rulebooks, and bam! You have one kingdom ready to play, with all sorts of tricks you can try to figure out, then mix them in with the rest of your collection. Thoughts?
