So after the initial release, I am planning to make a couple of small changes to the game play, such as a weapons overheat for the lasers and a credits page in-game. But for a massive update, I have started to work on other levels. I was wondering, should I make this an open world game, or a level based game? By open world, I mean a campaign stretching over multiple systems which you could visit whenever you want, and your overall goal is to destroy the empire by building a rebellion. It would still keep the same core game play though. Or maybe a level based game where you have to progressively destroy larger ships, and you can upgrade your ship along the way to specialize it, and perhaps hire others to help you out and build a rebellion in that way. What do you guys think?
