Ok, Im thinking of wildly upgrading my solar, metal mine, and crystal mines. I am looking at level 20 for each before I start defense or ship building. Would this be advisable. Will I be opening myself to attack. I do not plan on putting up anything in orbit until I have very high mining levels to keep the bullzeye off my planet. Should my next investment be a rocket launcher? Will this ward off any small attacks? I have been reading for hours and there is so much info on this thing. I just cant decide other than I dont want to follow the standard lines. Any thoughts?
