Don't know if this has been discussed before figured I'd bring it up. If you look at any of the great sci-fi out there ie: star treck, star wars, bab5, etc. There is always a flagship. Take the super star destroyer Executor from the empire or the Enterprise from the federation. That is something I think that SE4 is missing. The ability to build a flagship for a fleet. Obviously there would have to be a limited amount an empire can build if not just one. But maybe tie it to population or something. Every 20B people you have you can make a flagship for a fleet. As for the size of it. Make it ship research 12 after baseships and make em bigger then baseships but not as slow. Also they should use the dreadnaughts pic not the baseship. Of course this ideas probably will never be used in SE4 but it's still fun to discuss for SE5
