There are so many awesome ships, but my favorites by far are from Star Wars
Ebon Hawk from KOTOR:
Stinger Mantis from Fallen Order:
I think the reason I really love both if these is how they just feel intimate and cozy, like proper homes in space.
Don't get me wrong, I'm a huge fan of bigger ships as well. For example, I love the Normandy from Mass Effect. But in the end, nothing can beat small crew ships for me.
