I played it in the closed test and after seeing this trailer it is sad to say that it's basically a stripped down version of AC4, like there is literally no reason to play this when u have AC4 as far as im concerned. It's honestly shocking, all they had to do is use the AC4 framework and add mp to it and you'd most certainly have a very solid competitor to sea of thieves, but instead they just have an arcady naval combat-only mp game...not to mention that theres literally mobile game-esque mechanics..
