and why is it that the colonies in space were shaped like their countries on earth?

neways, this was the first gundam series i watched, and it rocked!!
the best parts were episode 40 onwards.
furthermore, the love between rain and domon just makes so much sense.
you know, its not love first sight and all.
they went through a lot together, so love just came through naturally.
though i think the final love sekiha tenkyoken was cheezy, but exhilirating nonetheless
oh yeah, where can i get the 2nd op mp3?
