13A has apparently never shown up in the NYT before. I have learned to play one of his pieces on the piano before though, so his name was fresh in my mind when I built this crossword.
this took me 7:49, but i came from dfac just to tell you how much i loved this puzzle. i loved the themers, and i loved the clues that spoke to me as a gamer. i liked 10d, the cluing for 59a, 72a, (i thought 72 would be another video game clue). hats off for leroy jenkins in 4d.
i don't have much else to add, i just had a really nice time solving this puzzle
