Black Flag being my favourite of the Assassin’s Creed games I had high expectations I honestly didn’t expect Ubisoft to meet. After a week(ish) with it I can say they broadly met them.
There’s a few things I certainly don’t like. The new microtransactions are a major sore point as well as the new upgrade system, namely for Kenway. The removal of the other weapon types is something I’ll sorely miss personally, I found it fun to play in different styles while freeroaming and starting fights. But ultimately I’d say there’s more positive changes than negative.
