I have played the game through 3 times now and I am currently playing my 4th. I am currently on Nar Shaddaa and I am having problems with quests that can not be completed. Dialog options that should appear, do not. Cut scenes that should appear do not. Thus preventing me from completing a quest. I have done everything necessary to complete the quest but the game won't let me. The only way to complete it is to load an earlier save and do it all over again (and before anyone comments, I run through the same way as before and can complete the quest).
I have also had numerous freeze-ups at various places in the game and numerous black screens, some while trying to save a completed level. Luckly I learned to make numerous saves at certain key points so I can reload when this happens. These Bugs/Glitches are not due to a back-up copy, I purchased my game. I believe they are due to rushing the game to the market and not fully testing the game.
I have never played a game this good, that had so many problems. Suggestions to Obsidian and Lucas, test your games before you release them. These problems will play a major role in my decision to purchace any game develeped by Obsidian in the future.
