I love sci-fi stories where there is a cost to using FTL travel – either a civilisational cost (like it’s a monopoly by a corporation, planet, or state), a dimensional cost (the FTL space is another dimension, and their inhabitants are not very happy about you punching holes into it), or a horror cost (you risk shearing your vessel in half or the calculations are so imprecise that you risk your vessel getting clipped into a planet)
