My personal WHY is to create a game with epic space battles, an amazing single-player experience, an expansive universe unique in that it changes, and a game to enable the creative to be their very best.
To me, other Indie games, such as MineCraft or Terraria, are great games, but have their faults for either PvP or creativeness. A good example is how I discovered StarMade. A hardcore player of Mine craft until recently, I heard about "MineCraft, but in Space" while on YouTube. I then stumbled onto Saber's ship review videos, and my inner creator woke up.
The point is, to me, starmade is a game where a creator, or explorer, or a player vs player guy can go nuts, but what is glaringly in the way is that there are balance issues. All ideas above have their merits, but what I see missing is single-player aspects.
As I have seen many times, not just on this thread, is the idea of ROCK,PAPER,SCISSORS. My problem with this is a large enough ship ( not very big) can hold all three, which I agree with, though I believe certain issues could be removed by eliminating multiple weapon classes on a ship. Bigger is better, currently, but I'd like to see a smaller/specially designed ship break another in two.
As for adventuring/exploring in StarMade, I personally like to land my ship on the surface, or fly around it in-atmosphere, which makes a small ship practical. But a small ship in space isn't practical, or at least, not very easy to survive against other player or even upgraded pirates.
I agree balance issues are a problem, but let's look at both sides of the coin, both single and multiplayer. That's why I believe certain franchises are not good anymore.
