it was mostly good and it had a killer atmosphere and good presentation, but what it lacked the most is CONTENT
all the side-missions are worthless and there aren't enough in-game events, plot twists and such for you to care much about what's going on
at the end before you go to the last level they found a cheap way to explain everything that's going on, intead of adding you know, 30-40 hours of proper content to the main game and let you discover the truth on your own as you play
the UI and the weapon system along with the stats were too dumbed down, too
and it wasn't any revolutionnary, it's still the same Bioware good vs. evil kind of RPG, the conversation system is a complete gimmick
