...the crew member rooms for "R. Hunter" and "M. Kusanagi"?

I chuckled when I saw that. There's also one for who I believe is the girl commander from Martian Successor Nadesico.

Very cute little references.

I'm happy to say, it's one of the first things I noticed about this game years ago, and it pleased me to no end.

Yea. I recognized a couple more too. "N. Izumi" and "A. Shinohara" are Noa Izumi and Asuma Shinohara from Patlabor. There is one more door there though, and I have no clue who that one is supposed to be.

Speaking of M. Kusanagi, I saw that one of the companies in first city is called "Batou"
