I haven't really noticed the soundtrack in-game, but I guess that means it's working (like in DBZ before the Freeza Saga).

Something that's bugging me are the bugs in some missions. I can't tell if I'm doing something wrong or if it's a bug, so I end up searching for it online and sometimes get spoilers. One I've found for sure is the Hanar diplomat side quest. Supposedly if you leave Citadel before completing the mission, you lose the ability to complete the quest. That's not really a spoiler, just a warning.

I may have found another bug but it's minor, finding someone on Citadel who needs turret parts I found on mission.
