I recently bought the AC: Liberation / Freedom Cry Bundle and Black Flag. Been enjoying working my way through Liberation. Just curious. Of the 3, which is the most enjoyable storyline?

You have some awfully vague thread titles.

Black Flag is my favorite of the franchise, in setting and gameplay, I never closely followed the AC plots so I guess I shouldn't have replied.

Have you played the previous ones?

I played all of them up until AC 3. I started that game and then I just couldn't continue, I lost interest. Then I kept reading reviews on how bad it was. AC 2 was really good, and the one after that.

Of the ones you listed, I think Black Flag is the one with the best reviews.

Black Flag is the only one I've played. Thoroughly enjoyed it.

The only one I've played all the way through is Black Flag which I honestly found to be a chore to finish. For some reason I've always wanted to like the series more but it doesn't do a whole lot for me

2 is the best one. 3 supposedly sucks, never played it. Black Flag is all kinds of awesome too. 2 is still better though.

Of the three you mention, Black Flag is by far the best. It's also like twice as long as the other two put together; Freedom Cry is an expansion of Black Flag, and Liberation is an expansion of AC3.

In terms of the whole series, I'd rank them from best to worst:

IV: Black Flag
Brotherhood
II
III
Revelations
Original

Haven't played Unity or Rogue yet.
