Just played a campaign with only four ship designs. Three fighters, one frigate (ion speed). I played Tribe, wanted to try out their fighters. Not sure I had the fastest designs but 3.xx speed rocket fighter and dual laser serenity hull.
I played 21 gun fighter until I had lots, then frigate spam for the North-West, North-East, and South-East.
No need to build a single cruiser (I actually have only the four designs I played the campaign with).
Oh, yeah, 401 turns. I’n not a speed deamon like LKohime…
