Cool story bro :) Sorry their AAs sucked so much that they had to find greener pastures :smug:
Anywho, kabirgph, as someone in this thread might have already said, larger AAs tend to have better culture than smaller ones; however, smaller AAs tend to have a tighter group. In the end, most AAs will teach you how to build your nation efficiently and get along well with the community. Goodluck and have fun in CN :)
