Godzilla: Pack of Destruction

I recently picked up this Pack of Destruction toy set. All these figures are about an inch high, but still highly detailed. Very cool. I'm not a huge toy collector, but when Godzilla figures come out in America (especially from Bandai who are the masters of Godzilla toys) I usually pick up a few.
I'm curious as to how they chose the monsters in this pack. Obviously, Godzilla, Mothra, Gigan and Minya are well known characters here, but Moguera, Destroyah and Manda are pretty obscure to the casual G-fan.
Anyway, they are well worth picking up if you want some cool little monsters to cover your desk. Next I have to pick up the Crumble Zone, which includes a King Ghidorah and a Baragon (another unusual choice.)
It's a good time to be a Godzilla fan.
