I love this game, but it has been massacred. The developers were rushed in this games creation, so they cut a LOT of stuff out. (An entire planet and many other things were cut from the game.) Since it was rushed, the makers didn't have time to fix all the bugs and glitches. The consenquenses being that many side quests may not be completed and your game may crash from time to time.(It is NOT a dirty disc, do NOT clean it unless you're sure its dirty). Save very often and in different slots. (TRUST ME, DIFFERENT SLOTS FOR EACH PLANET). Despite all the flaws, the game is still great and the story (which had so much potential) is amazing. If you loved the first, play this but don't expect much of an ending.
