***** NOT A TEACHER *****
Hello, Optimistic Pessimist:
I have been thinking about your question for 24 hours, and I now realize why SoothingDave and Barbara said that "other" would
not be an appropriate word for your sentence.
*****
(1) I think that "other" would be appropriate only in something like:
"It will be popular in places [which are] other than New York." That is, popular in places that are not New York. But I read your
link, and that is clearly not the meaning. (Thanks to the one and only Professor George Oliver Curme for reminding me of the missing words "which are.")
(2) The word "more" in your sentence makes it a comparative sentence: It will be popular in more places than New York.
(a) My books tell me that if the words "more" and "than" did not exist, then we would have to express this idea something like:
It will be popular in places beyond the degree in which New York is a place.
(i) For example, "He is taller than I" would be "He is tall beyond the degree in which I am tall." (This is a theory of many books,
but Professor Quirk's magisterial grammar does NOT agree. For us ordinary speakers, however, this theory seems really neat.)

Thanks again to you, Spongie, SoothingDave, and Barbara. I certainly learned a lot.
