Favorite Shipset: The Y'Gathian Freestates as done by Andres. (damn fine set, still my top favorite after all this time).
(runner ups: The Slaneesh(sp?), Classic Star Wars Empire1, Solarion, Rage, The EEEvil......)
Least Favorite: None really, all are just reflections of the shipset designer's aim/desire. I can't really say "That is crap!" cause I can barely draw a stick person.
That being said I just wish the Sagella/Praetorian shipsets ships were bigger on the main map.
