True, but the game has restrictions, with there being no "Abandon Ship" and being either rescued or captured, nor having an alternative to having to quit your career after running out of fuel just short of a base with fuel. There is no way to have a vessel come "tow" you into port. Traveller used those restrictions to attempt having a semblance of a viable alternative to being helplessly stricken in the middle of nowhere, with dead engines or inoperable rudders, by having a submarine "dispatched" as a repair vessel. You still had to make emergency repairs on your sub, and then get to the "rescue" location, which wasn't always possible... Some folks like the mods, others don't, but there is no elegant way around some of the game's issues.
