Welcome to the forums, @johnnybeegoode! Black Flag is my favorite game from the AC series, though I've admittedly only played 3 of them.I have really enjoyed the game. It has been buggy at times but nothing unlike most new releases (that I can think of); the campaign is a blast and although I don't think it's "Black Flag" status ("Black Flag" might be my favorite video game of all time; closely followed by the Far Cry series), I think it's worth retail.

I don't plan to pick up AC: Unity, but the guy who keeps trolling @Chandler Wood in random comment threads about his review on PSLS is hilarious.
I completely disagree with that review but i'm not going to be a crab about it I just disagree with it. Finished the game a few weeks ago and the ending is horrible, story is barely tolerable but the gameplay is fun and co op was great. I'm not reviewer but I would have given it a 7.
I wish more people would take your approach.
