I got the game a few days ago, i was in a rush so i didnt design my guy, just a soilder, i beat the game in a rush also, like i played 16/7 and I was a good person i got the 75% paragon acheivement. I think its a great game just like a better version of jediknights of the old republic which was a great game also.
try getting as many side missions as possible. I went through my first run-through slowly and I enjoyed every bit of it. I think it took me about 30 hours.
