I'm not 'quick' to 'embrace the nuBSG' but I can see why people are comparing the two. Voyager didn't need to be so dark as BSG was, by anymeans, but Voyager should have been a little more like that series, while keeping the trek parts (visiting new worlds, species, etc...). In the first few episodes, Janeway (and I think some others) kept mentioning that supplies on certain items would be limited, but after that, the 'limitations' didn't see to be so much as a way to craft interesting stories, but to keep the status quo (such as Neelix still being the cook).
Even BSG wasn't great in that regard, whenever the resource problem came up they solved it for the rest of the series.
Water: The water supply is lost to space, by the end of the episode they find more and say their new supply will last for years even though Galactica has to supply 50,000 people with a hold designed to supply 2,000. We never hear of it again.
I'll give you this one partially, their system was designed for the crew of that ship, and not an entire fleet as it was. However, one minor note, the system was also said to be good enough so that it was able to see continuous use as it was, for several years, before requiring a refill so to speak. In other words, in day to day operations it seems, there's little lost in water, despite thousands of people taking showers, using the toilet, etc...
The Hand of God: Galactica is running low on tylium fuel, they destroy a Cylon base and gather enough fuel to last for the rest of the series.
Yeah, we probably should have heard about this again somewhere, I think they probably just figured they were able to store a large bulk of it somewhere and process it as it was needed, and the vipers didn't need it as much due to their motion in space save for maneuvers. The worst of it was, it was also use for the FTL's, I think and I believe it was mentioned the FTL engines like their fuel...
Scar: They spend a month (one episode) mining an asteroid for ore to build new vipers using Pegasus' magical viper production facility, and we never hear about a lack of fighters again, even after losing Pegasus.
I seem to recall it being mentioned a few more times, actually but it wasn't an overly massive problem because the surviving Vipers from Pegasus had combined with Galactica. The core problem they had afterward, due to deaths and mutinies and the like, was they had vipers, but not enough pilots.
The Passage/Eye of Jupiter/Rapture: Somehow all their food is destroyed so they collect algae from a planet, and they don't finish collecting all they need before the planet blows up real good. Somehow that algae turns into a limitless supply of coffee.
I was curious about this to, somewhat surprised they didn't somehow have a way to grow food within the fleet. I just figured they had a minimal amount, what they could get by on and a 'this would be nice, just to be safe' amount, and the fleet ultimately left with the minimal amount. Been a bit since I've seen the episode though, so I don't remember for sure.
And they never run out of munitions. That explosive screen they do during battles must be terribly wasteful, but their guns are still operating right up until Daybreak.
They did address this, perhaps it's not totally believable, but they mentioned several times, and even showed once or twice that Galactica had hired people to make ammunition, and that's pretty much all they did.
One of the great scenes from 33 was watching Tigh rationing his final bottle of whiskey, but how many times during the show was he completely wasted?
Yeah, I always wondered where they kept coming up with the booze. He must have taken part in the still the deckcrew made in one of the supply closets in the hanger deck.
