You dont need to be rude.
Some of these details I obviously cannot give because I played for about 4 hours. My friend got the platinum for that game before launch, just like he did with RE3 and TLOU2.
As for the sideques, that's exactly what I said. There are some good ones, but most are simple with mere objectives on the map. Most resemble quests from AC Origins and AC Odyssey, with the npc asking you to save someone or to free a village.
You wont stay 5 minutes without having your attention drawn to a point of interest, a random combat, one of dozens of side quests or a fort / camp to be taken. Then you go there with the very essential guide wind.
Tsushima has no reference points for the player to be without the map and at all times has some repetitive task to do.
I realized that with 4 hours of play, imagine with the 50+ that the game has.
My friend and I really like the game, but not because of the sidequests, since the really good ones are those focused on specific characters.
