I agree with Barta. I experienced several bugs with BD, but most of them were minor annoying bugs. Overall, I would give BD 8.5/10.
If you were trying to play BD with one of the 1st release patches or an unpatched version of BD, than I can understand how you could have experienced alot more bugs and more serious ones as well. If you have the time and you still have BD, download the latest patch, and start a new game. Maybe you'll have a better experience with BD. <img src="/ubbthreads/images/graemlins/up.gif" alt="" />
