As quite a few folks (starting with Don Murphy and Buzz Dixon) inform me, the word "cosplay" does not come out of the gaming world. It's more from anime — a term created by squishing the words "costume" and "play" together. Credit for its coinage is often given to Nobuyuki Takahashi of the Japanese studio Studio Hard and it's said he invented it while attending the 1984 World Science Fiction Convention in Los Angeles. Others say it predates him and that event but we don't need to get into that. Thanks to all who wrote in.
