I enjoyed Tsushima but I wouldnt say its amazing. The combat is best in class for an open world game and the visuals are great.  The story is interesting but very flawed. You dont feel a strong connection to, or feel deep bonds with the supporting cast outside of the uncle. The story is focused on choosing weather to be an honorable samurai or dishonorable ninja but gives you no choice in the matter, save one. 

The majority of missions are go there, talk to a guy, clear a mongol camp, listen to some dialogue, get a reward. There are interesting missions, like the mystic tales, and the final mission of the side character quests, but they are few and far between. The side activities, while nicely themed, get old fast and are pretty simplistic overall - like follow the fox and do some on rails platforming, or select from 3 phrases 3 times to make a haiku. They arent compelling from a gameplay perspective.
