There are so many 1/2 made ideas and non-updated tech, buildings and ships. Instead of killing yourself coming up with brand new artwork and tech, why not have raid prizes to update the older stuff, new tech token, it can change tier # and add a newer look with better stats, ie the foundry. In the build menu the older stuff can still exist along with the newer items. The buildings, R&D, shipyards, and older concepts can be better developed instead of adding wasted stuff we will never see or fully develop. You can even change the name slightly to signify the change. The results would be the same building times and such but with fewer similar ship silhouettes to figure out, ie, as the ship becomes older tier compared to the current it turns a brighter color so the newer stuff is still subdued.
