ARBITRACOM
Sic transit gloria mundi
Random question - Does anyone know where the Orel Sea is located in the real world?
Plus that game was the start of a continuity reboot, so it was a good starting point, and the first game to be playable on Windows rather than PC-98, and generally was just a big step up in visual polish and such. (Albeit now pretty dated compared to more recent games.) All of that combined really helped give that game an edge in attracting people's attention, and as they say, the first installment always wins.
And because of the 'feeding the duckies' thing. 'Impoverished' is an interesting role that nobody else really fills, that has a lot of comedic and dramatic tension built in.
According to the KanColle wiki, Orel seems to refer to this:
