Once you make it your own, yes, it is YTU. If you are discussing the published setting though, no, it is not YTU, it is the published OTU in its many variations.That’s a fine opinion, but it’s not generally how RPGs have worked in the last 50 years. The setting is only a starting point and we each make it our own.
You can change the name of the Third Imperium to the Third Galactic Orgy. Doesn't matter. That is IYTU, not in the published material. If we are discussing our own personal TUs, then yes, by all means share your creativity with us. If we are discussing the officially published setting, (even with all of its errors) then discussing the Third Galactic Orgy isn't really germane to the discussion.
