Greetings.
I've been exploring sins beta 2 for some time now and I find the game to be very nicely done.
There is one particularly aspect, however, that is a bit off in my views and that is the production and use of the 2 side resources, metals and crystals.
Most things require both, more metals than crystals, a few require only metals, but... there is way too much metal or way too less crystals or both.
I do not mean asteroids, those are more or less equal, but I always found myself with an overabundance of metal and a chronic dependency on crystals. So much that metals has just become the trash resource to sell to the black market for credits, cause I've never be out of metal, I run out much much sooner of credits or crystals.
I would suggest to tone down the metal production (or tone up the metal costs) and to tone up the crystals production(or tone down the costs) a bit so that you could have deficiencies of both and you would not have a "trash" resource.
Of course my experience is limited, but that is what I found out so far.
