The reason I see mining ships being integral to DU is a simple one Scale. Now imagine this you have a large organization and you want to start getting into bigger projects like large factory's, ships, buildings, space stations, etc... But you need the resources to do so and so you need to mine and mine and mine some more. Now just think of doing all that mining by hand, doesn't sound like so much fun does it? That's because it is not its just very very tedious and boring. However adding a way for mining ships to be in the game would easily fix that problem from down to the solo player that wanted to get into mining but just got sick and tired of going in a deep mine and digging his way all the back up to the surface every single time to the big organizations that just want to keep up with the demand of there projects. Mining ships would fix it all! Now in a game that focuses so much on the grand scale of everything it has to offer mining just doesn't seem so grand. Now I already can see several concerns here is a few that I think can be solved.
Q1. Wouldn't the calculation of voxels collisions and destruction be to much?
A1. I do not think so not if they take the current scanning/mining system that is already in place and simply apply it to mining ships.
Q2. Doesn't it have a high chance of inflating the economy out of control and put those who have bigger mining ships richer and those who do not poorer?
A2. Possibly but as I stated earlier by taking the mining system that is already in place and applying it to mining ships they could very easily change the stats, values, and gather rates for these things to balance it out. Also doesn't someone who spent all that time, effort, skills, and resources on focusing and making a big mining ship deserve to have there mining operations be a bit more lucrative for them?
Q3. On release date wouldn't everyone just go for mining?
A3. Maybe in the beginning to get some money under your belt but ask yourself this. Would you go for and stick with mining? On release I am sure there would be many many more exciting things you can and would rather do within the grand scale of this universe than just mining.
Not convinced because you have several concerns? List them down below! I would love to hear your thoughts on the matter!
