Their ships are all fuelled by hydrogen, the most common element in the universe, so I don't think it would be a problem. They'll just have to hop between systems with gas giants, all of which are an (almost) unlimited source of both hydrogen for their rockets and helium-3/deuterium for their fusion reactors. And while they refuel, they can discharge their drive core into the gas giant's magnetic field.Blachman201 said:But the problem is that ship travel are still very much limited by fuel supplies, so unless someone goes through with the painfully slow method of building a long line of fuel depots, travel can pretty much only happen within local clusters.Seneschal said:I have to say, I like (or rather, I appreciate) the endings. I found it gratifying that the galaxy could not be saved quickly and cleanly by the McGuffin weapon, and that galactic society must be almost undone completely if it's to break the cycle.
Everyone seems to forget the races still have FTL travel. From the ME Wikia:
This means that the Milky Way (~110,000 light years) can be crossed in about 25 years (not accounting for stopping to discharge the drive core). Besides, the very nature of colonization and fabrication technology (the omni-tool is an all-purpose fabricator) means that most space colonies and habitats DON'T depend on interstellar trade to supply them with food. Self-sufficiency is almost guaranteed, so the only thing they have to face is isolation. Not that much of a downer, is it?With a mass effect drive, roughly a dozen light-years can be traversed in the course of a day's cruise.
Also, many of the species' heavily populated homeworlds are hit very hard by Reaper attacks, and without supplies from the outside, rebuilding is going to be an extremely difficult process.
It will require a lot more time and a bit of lateral thinking for the galactic races to adapt, yes, but it's definitely not something that would stop them. They'll still have it better than most other sci-fi franchises - heck, their travel speed is double that of Star Trek! (end-to-end of the galaxy in ~20 years, as opposed to the 70 years (without shortcuts) that the USS Voyager needed to get back from the Delta Quadrant, a trip of 70,000 ly). And if Star Trek has a prolific interstellar civilization, I don't see how the citadel races are doomed.
