2: As far as i have been able to get info, there is/will be a mission system that you can use to get credits.
This as a new player, in the future, will be a good way to get started. but there is a but.
How long will it at that time, take a new player, to get enough credits to buy a ship capable to go toe-to-toe with someone outside SZ?
if it takes to long, they will loose interest.
In My experience, it should take 2-4 days (12-24 game hours) to be able to refit the laborer with armor and 1-2 guns.
spend more time doing missions, be able to buy better armor
Asteroids in SZ respawns at a random time.
Could be between 1-4 weeks, and required to be mined out completely for the "countdown" to start
Leave a single pice of an asteroid left, and it will not respawn
This gives new players the oportunity to make some money while being safe, and trade their way into the items they need to build a ship.
They will have to put in a lot more time, as they do not know where or when an asteroid is going to respawn.
