Only two problems jump out at first glance

Can I ask you to specify how many ships and worlds? Right now the nation with the most worlds holds 32, while the largest number of ships currently in active service to be around 550 IIRC. While you mention hundreds of variations on each ship type and countless ships being made. Obviously it seems that there are other nations that have a tech advantage on you and you'd need numbers to help counter balance, but if you have way too many ships and worlds I'm gonna have to ask you to nerf. We made this version of the RP to stop the massive holdings and fleets which had developed. While they were certainly larger than yours because it ended up very ridiculous (towards the end I believe we ended up with about 30 mill ships in combat at one point), we can't really have someone have a huge space ship numbers advantage and just drowns his enemies in space ships

The other problem is the 830km battle ships. I think the largest ship fielded in this rp is fielded by myself, there's only one, and it's not even a 1/20th of the size... And is considered so expensive to supply that it only exists so the Supreme overlord can brag, and would ever really gets used in conflicts over the Triarian homeworld. While bigger =/= better, there's not denying you can put a shit tonne of guns on 830km of ship or simply plow enemies aside. I think 830 km is too long, it wouldn't really be worth fielding in any battle.

EDIT: If anyone has come back to read this... what on Earth have you done that for?
