I actually agree with both das and emu. I should've gone for only two cradles, which is a pity, since I did indeed consider it before I started the NES.
The choice therefore falls between working with das' suggestion, or rewriting some of the original history and deleting one cradle and moving its residents to the other two...
Will decide on this later. Anyway, deadline has passed, so those of you who have not sent orders, kiss your nation goodbye and make a new one.
