I am really rather enjoying this game after about 25 hours of play. There are a few bugs there, the one I have come across is that the drinking game is buggy (on Ps4) if you take part in it you are drunk every time you reload so leave it alone.
I do find the map a bit small compared to Assassin's creed odyssey but I know other people found the map too big on that game so that's a personal preference.. The game is decent, graphics are good. It's not blowing my mind just yet but hopefully it will soon.
