Ive seen the videos of the sins beta on the net, it had so many different types of ships and i was disapointed that not all of the ships in the beta were put into the full game.
expansion pack
* all that stuff about grav well increase and planetary defences etc
* new ship( like the once in the beta )
ive also played a mod called sins plus bye Uzii and it add new types of planets and stuff, put new planets into the expansion.(oseianic, industrial, urban, toxic, forest and a ship gravyard).
and loads of other stuff like new buildings and storyline.
