Hope you enjoyed the twist and used the missing letters to find the hidden cross country. The first two crossings were probably the hardest to get as you are trying to figure out the Thursday theme. Especially if you entered LASTNAME (First in China, second in US) with confidence. Once the grid was partially filled and the central CROSSCOUNTRY revealed, did the crossword staples (PANAM, BEIN, IGER) provide the confidence to skip a square? At least that was my attempt — that the puzzle put up some initial resistance and then crumble for an easy solve!
As usual, great work by the NYT team on the clues that were changed - they know how to clean up some of my wild clues and create a balanced offering. One of my misdirection clues that did not make it: Probe that ended September 15, 2017 for CASSINI; and that hard TONG-as-a-verb clue? Not mine!
The first version, started early in the pandemic, was a simple letter-drop from countries and you can see a better version by Deeksha Gaur, a brilliant puzzle! In a strange coincidence, an early draft of mine had identical theme answers (but, without the great revealer: NATION BUILDING)! Uncanny how two constructors can independently dream up similar themes.
But I dropped this format and looked for two countries that could cross each other with the same missing letter. Why? Because I did not have the wonderful NATIONBUILDING as the revealer, and CROSSCOUNTRY/UNITEDNATIONS/MISSINGLINK were the potential revealers stuck in my head!
The second manifestation, a Sunday 21x titled "CROSS COUNTRY", with UNITEDNATIONS crossing MISSINGLINK in the center (perfectly at the N!), had six intersecting countries sprinkled around the large grid. (LEANON-OLIVIA, MAN-CAMERON, HANA-REECE were some of the other finds). However, the missing letters did not spell a country or a revealer. With some crisp feedback from two test-solvers (one with initials BEQ, and the other named Patrick with a ™ symbol), I dropped the puzzle down to 15x. Both stalwarts insisted that the missing letters had to spell another country to add an extra layer of fun, so I had no choice but to find BEIN-IGER (the weakest of the crossing countries). Thanks guys!
List of other countries on my list: HUNGRY (really wanted to use this, and I am sure a better grid-expert would have figured out how to use this with PANAM/TONG/CHIN/MALT in the 15x version, instead of the TONG-PANAM pairing), INLAND, ENYA, NEAL, PAIN/SPAN/SPIN. Did I miss any others?
