Been playing this for a while. Been enjoying it. I really like the loot system in this game, it's better than a lot of actual looter games out there in that it always feels like a better piece of gear is just another gameplay loop away.
Do think maybe the world is too big. Also there's a lot of sidequests and they're more or less required in order keep up with the level ranges of the main quests. Would have preferred if they were a bit more optional as they are pretty hit and miss.
Also as fun as the world is to explore, and as much as this game gets compared to Witcher 3, I think they are missing some very key components that made the Witcher 3 great instead of just good, and that's the story and characters. They just aren't very good here. There aren't a lot of great supporting characters that you really get attached to imo, and while the main character himself is good in that he has a solid and likeable personality, the overall narrative feels a little sparse and drawn out.
Even so, probably the best Assassin's Creed game I've played. Combat is fun and the core gameplay loop is fun. And the story is by no means bad, just feel it could be better, especially with how long the game is.
