Yeah, but they found ways to make them so goddamn fugly... they darkened the colors, added absolutely godawful striping to the Galaxy-Class, gave red and blue engine lights to ships that never had them, like the TOS Connie, and some of the other ships just look plain awful.
It's the players who choose hull material, -painting and so on. If you prefer it, you can still go with the standard white hull look and don't put any stripes on the ship.
I guess, back when I did it, the entity was just ridiculously easy. They've buffed the thing quite a bit in the meantime, it seems.
