If you believe you will fail, you will. If you lack imagination and creativity, maybe StarMade is not for you and you should stick with linear, story based game.
If you want to play StarMade and improve, your overall enjoyment of the game will increase. Yes, there were times when I might have given up on the game. I have tried several different ones over the last few months but StarMade has captured my imagination and my desire to be creative. If you don't want your ships to be lifeless grey monoliths then copy someone else. I am often astonished at the designs of other players and use them as inspiration for my own. Even a few blocks or a combination of different hulls, lighting, wedges, slabs, etc.
Close examination of my ships and station will reveal elements from Lenscap, Drakkart, Jacemachine, Gmodism, Aceface, FuseMC, Sven the Slayer, Skylord Luke, etc.
StarMade is an utterly absorbing game and I would recommend it to anyone who has an ounce of creativity and the desire to learn and improve. If you lack either of these traits, then you really won't get a lot from this game.
