Well I never said "enter" stations, I said travel between them. In X3 you used SETA to travel between stations and in X:R and X:4 you had (super)highways. Freelancer also had those rings that speed you up and you could leave them at any point - in fact, the way piracy worked was you destroy one of the rings which would interrupt the travel and drop any ships out of the hightway lane so you could attack them.

Basically, all of these games didn't just have a loading screen when going from one station to another, there was an actual feeling of distance and travel. From what I've heard starfield doesn't have it at all.
