Another thing I was also thinking of is (if it's possible to do with the game engine) to have the Mega-ships build as a structure (you gotta figure a ship that size wouldn't fit in a cap ship facility). That would balance it somewhat a little more, in the fact that it can be attacked while under construction. Another thing that would be cool to see is if they have to be built in stages. IE. Stage 1 Building- Builds the ship, upon completion it can move like a normal vessel but only has the statistics of an average battleship. Upon clicking an "upgrade" button it again turns into a non-movable object or structure type item and begins another build phase. Stage II would make it more powerful with the firepower and armor far above that of a capital ship, with Stage III completing it and giving it "special abilities" like capital ships (as opposed to the capital ship's "Experiance" based upgrade). The dreadnaughts would have to still be incredibly slow, just to keep things even. Possibly even make them half the speed in phase space so the enemy has time to react if they can see if coming (another idea that might balance gameplay a bit). Just some ideas i'd like to kick around there, see if anyone else is interested in such a thing or has some input.
