Clearly we are a broad church and our differences of opinion should only be celebrated.
However, I shall defend my standpoint one last time before retiring.
Firstly, the use of the word tautologies seems a little harsh, suggesting somehow an erroneous duplication of words or phrases which I certainly haven't seen in this puzzle.
Also, the suggested title That's Life might not have been ideal as 'l' is not listed as an abbreviation for life. Otherwise it may well have worked nicely.
Finally let me just re-iterate that my own preference is for the purist skill of completing crosswords. The use of devices to make this more difficult by preventing the use of previously solved answers to partially complete unsolved clues is very welcome.
However, any 'end game' which is superfluous to the completion or translation or verification of the grid is in my view unnecessary.
*Spoiler Alert*
There has been talk of the PDM - which can be fun. In the case of this crossword my own PDM was completing 10a (my final entry) which had me troubled for a while. A further, more thorough reading of the preamble helped me out and gave me cause to smile.
I'm sure many of the setters read this and another forum, and therefore whilst there are those looking for more riddles and cryptographs, I hope I speak for those with more purist tastes.
Until next week then.
