I don’t think fast travel is the problem. The problem is that there is an actual “exploration” part of the game, where you wander around planets scanning things and looking for points of interest, but it is by far the most boring part and I have not had much fun when interacting with it. There is nothing exciting to find, and it primarily rewards materials that I mostly haven’t had a lot of use for, because when I need something specific for research or crafting I can buy it at the store, because materials are nearly worthless in terms of credits.
The mini-dungeons and other points of interest you can find need to be way cooler for the wandering-around-on-planets to be worthwhile, and the actual exploration gameplay needs something more than walking across plains and hills in order to be interesting.
The best parts of the game are when you pretend it’s Fallout In Space and hang out in cities doing quests for randoms.
