I played the first bit of the tutorial. I'm way too early in into the game to have an opinion yet. I'll get into it a bit this weekend and we'll see how it goes.
Played for about... 6 hours? And I haven't done the "Proving" story quest yet. So I'm still running around the starting area.
The game is far more Far Cry, less Skyrim. But it's not a bad thing.
I think this game is going to be shadowed by Breath of the Wild though. (My Switch and copy of Zelda will be here on Monday, so I'll be playing Horizon over the weekend).
