Brotherhood and Revelations continue on from AC2 with Ezio's story, I enjoyed them both.
How do you know the MP is shit if you never played it? If you care more about the achievements in terms of boosting etc then don't bother.
If you are going to buy it, Brotherhood has DLC to get the 100% and good luck on the 100% sync.
