Something I would like to see in SE is more stuff to do in survival. The core gameplay is amazing, but I regularily feel like there is no aim. No goals. No reason to build anything except the fact that it's cool. Let's say the space pirates had lots of bases, vehicles and fighters scattered around all the planets and in space so that there's things to defend yourself against and things to attack. Ofcourse the difficulty would increase from earth, to space, to the moon, to mars, to the alien planet etc. Maybe even quests. More NPC vehicles to fight basically!
