Mass Effect 2 has had a lot of hype and clout surrounding it since it came out, and while it certainly is an above average title, it's not the game everyone seems to be making it out to me. Aside from the excellent storytelling, Mass Effect 2 has a lot that it needs to work on. Bioware did a decent job in listening to the complaints that the first title drew, so hopefully they can make part 3 the game that 1 and 2 should have been by listening to some of the things being said around the internet.
This is my personal list of things that I had issue with in Mass Effect 2. Hopefully at least some of them can be addressed for the third game in the series.
