David Braben confirmed in one of his comments yesterday evening that if you wipe your save in Beta, it will not affect your main game progress. I can also confirm that this has been the case with every beta up to now for all the releases since the game was released in December 2014.
I am curious to know if there is a way to actually reset only certain aspects of the game.
Many other games allow for multiple characters in the same account, where you can share among them items and money.
I would like the idea to actually have different commanders, each doing something different in a different area of the galaxy, and not worry to have to start with 1000 credits again.
Is there any technical reason for not allowing multiple commanders sharing one single account?
