Personally, I began to lose interest after Diki switched from play format to the actual novelesque style currently utilized. I found the plays a refreshing break from the standard style, and they did help to streamline the plot somewhat, if only by forcing you to think more about it.
I personally think this was a much weaker story than 1-5, probably due to the villain switch from Ecksian to Dinitridian, especially when I was expecting Ecksian to return. I also found the ending far too abrupt, and the bit about *i just confused me.
Criticism aside, I do feel that it is still very interesting, and I definitly enjoyed reading them. Most of your problems cound be solved like most of Ayn Rand's- you just need an editor to help prune the thing to keep it pretty.
