I am that one person. With 20 characters and the mission system, I singlehandedly can raise enough quanta in three days to cover the taxes to keep Madis Moon 1 for over a month. I can confirm that this is true. The mission system is alt abusable and it pays out too much as a result. It needs to be reworked so it doesn't provide such an egregious imbalance of quanta earnings, and so min-maxxing it doesn't benefit only those with alts. Some ideas that either I have had or have heard from others are...
- Why do I need 20 people to pick up 20 crates of bananas? If Feli needs bananas imported from Jago constantly, and someone has a ship capable of hauling 20 packages of them, why doesn't Jago just give that one person all twenty packages? Allow one person to pick up multiple packages of the same mission. This way, alts aren't required to minmax the system.
- If the above change is made, then the rewards on the missions also need to be adjusted to ensure that one person can't fund an entire moon for a month on only two days worth of missions (20 packages at a time).
Some people have suggested restrictions on how many packages you can carry, or how many missions you can do in a week, but those don't make sense. If Jago needs constant "Crates of Sand" from Symeon, they won't care if they get 20 crates from a single ship in one go, or if one ship brings them crates 20 times in a week. So, limits and restrictions don't make sense.
I've heard of some people suggesting that delivery missions could be procedurally generated and only able to be accepted X number of times. This one makes sense. Say one planet needs a bunch of parts to manufacture warp drives and another has an excess, that planet may put up a request for 120 packages, and people can accept packages until 120 have been picked up. The downside is that this allows one player to hoard all of the packages and leave other players out of luck.
Ultimately, game balance is delicate and very easy to throw off-kilter. I'll be the first to admit that NQ doesn't have the game balance perfect right now, but very few game companies have mastered game balance. Anyway, I wanted to put in my two cents since my moon shenanigans became a discussion point.
EDIT (adding math)
As for how the math works out, if I run Water Run (8.1 million per package), Territory Unit Parts (8.9 million per package), and Crates of Sand (9.5 million per package) in one day, that is 26.5 million quanta. Since I carry 20 packages at a time, that ends up being 530 million quanta. Three days is 1590 million quanta. Madis Moon 1 has roughly 1400 tiles (I don't recall the exact number). To pay taxes on every tile on that moon requires roughly 700 million quanta. Pay the taxes for one week, then let the tiles go inactive for 13 days. On that day, pay the taxes for one week to restart the cycle. It only costs around 1400 million quanta to cover the moon for just shy of 6 weeks.
