I can't wait to get Assassins Creed 4 Black Flag, it looks like it will be the best of the series. I think Assassins Creed may be the best game series I have ever played. It is one of the few game series that actually has a good plot and good characters to match.
The characters and settings are looking pretty nice, and the multiplayer seems the staple of series, so i guess i can expect some fun times to be had in it, specially in the game's release.
