"i was talking to a guy, who is playing the game, but he is not the reviewer, he said the game is pretty great overrall, graphics are one of the best of this generation. Combat its a mix of Nioh (Stances) and AC origins ( but better). He also said Side quests are great and very well done, and the missions is up to you to choose stealth approach or a more samira style approach. he said its not like a Wichter or a Breath of the wild in terms of interaction, but the game is very good and gives freedon to do what you whant to do"
There's a couple more posts in the link - No bugs in the unpatched version was about the only point of importance. Oh and no big cities discovered yet. I'd be surprised if there are any - in the context of the time period Tsushima only had a population of 300!
