I don't think ive ever seen a game that encourages user generated content quite like SR2. Installing mods, editing XML craft files, downloading crafts, creating entirely new solar systems to play in. Everything in this game is geared for the players to create and expand the base game.
I think if the devs added a few more functionality parts, and actually finished the campaign mode (You guys have promised it to us since the beginning. We haven't forgotten.) Then the game should be fully released and let the community build the game from there.
Shout out to sflanker and ComplexRockets for creating some amazing mods for the game already, I can't wait to see what happens next.
