Mission accomplished, game beat! Very nice ending, one we all know very very few real world historical pirates ever experienced. It's worth noting that unless you've played the first hour or two of ACIII you probably won't understand the significance of the mid credit cutscene.
I've already beaten the Aveline bonus material and started on the first official dlc freedom cry. Aveline was good for about 45 minutes of play, freedom cry has full crafting, merchants, over 10 chapters etc. should keep me occupied for awhile heh.
