Oh wow. Every ship for me was iconic, that was in perhaps most ways the whole point.
One of the closest thing i shared with my father was going to his office late at night and firing up Star Control 2 and playing some super-melee with him since the only computer he had to share with us was the one he had at work.
Star Control and SC2 understood intrinsically that ships’ behaviors need to reflect their personalities and sort of effortlessly and intuitively did so. Maybe the only ship in 1 or 2 that actually wasn’t any good was the Supox “fly backwards” ship. I liked in SC1 Genesis version how it had a “unit description” screen for the ships, really added to the personality of the game.
3, otoh, was a step down. I still remember some of the race names, but criminally the ships were mediocre, with little personality, and not particularly well balanced.
Star Control without interesting ship and alien design is like Tomb Raider without tombs or Civilization without nations.
