That is from Macross II and a different version of this was in Macross: DYRL. But for the most part it is the same ship design.
Now about this whole Robotech-Macross issues of what belongs to what and who is better than the other in terms of the shows and other subjects. Those are Robotech-Macross purist issues which I will not take part in.
As I have stated on a few other forums, this is mainly going to be a Robotech Modification. But I do intend on using more ship designs from other Macross shows in order to progress the time-line and show a level of new ship designs. This also means non-canon ships will be put into place in the game if they maintain the look and have a proper place with-in this universe. In other words it has to make some sort of sense to be with-in this game.
The original Mod concept was to full in the four race slots with the major races of the Robotech Universe which as we all know are the Zentraedi, Robotech Masters, Micronians and Invid. After thinking this threw a little there is simply not enough Robotech Master Ships to go around and fill in an entire race of ships for the one race.
So I can either place the Robotech Masters in with the Zentraedi and split the Micronians into two major groups the RDF and the REF with most of the Southern Cross ships in the RDF section.
Now SFC3 has a AI pirate race available, and a perfect choice would be to place some Marduk ships in that slot.
