I don't know about you, but personally, I despise the
Xiati in SF/SE5. They just look like a goth's wet dream, all red and black and spiky... In SE4, they were quite awesome looking. The bigger ships had that keen 3 wing configuration going. Pretty much every ship (save the stations) had a sleek, dangerous look to it. Even the colony ship looked dangerous! SF/SE5 version... meh.
It's not so much that the SE5 version is so bad per se, it just doesn't measure up to the SE4 Xiati, I think.
So, I propose to you, the shipset modeler, a challenge: Rebuild the SE4 Xiati for SE5 usage! Let's see who can come up with the best adaptation.
