This annoyed me. You can boost pack all the way from your New Atlantis penthouse balcony to the New Atlantis star port. Off a skyscraper, travel for miles. It’s fantastic - everyone should do it. Really gives a sense of the scale and capability of the world and game. It does that better than any actual quest or cutscene… bit of a missed opportunity if you ask me.
If you’re into that sort of thing yeah. It’s a good option if you just want to finish the game, but I like the experience and immersion of traveling around. And the game encourages that to some extent because you overhear some missions while you’re walking around.
I generally don’t fast travel unless it’s something like the High Hrothgar quests in Skyrim that had you going up that mountain multiple times.
