Hello,
So I have been created guides for Sea of thieves almost for one year now, the most and foremost thing I always here "In-game Tutorial is very Basic" and other players "I quit the game after a few days of playing, then came back months later, if it wans't for this video I won't know how to play" This goes for me and other creators. Without these, new players give up the game specially if they got it on gamepass since no one wants to waste their time feeling dumb.
I have seen Several Games where they have an in-game link with "Video Tutorials" where it links to top community channels and guides. People like me, Captain Falcore and several others spend hours grinding the game on a daily basis to help the community and specially new players.
The Bottom right Panel when you first launch the game should have a window for video tutorials, where it links to a page on this Sea of Thieves website showing each of our channels, or links to guides playlists. This way Rare helps the likes of me with further exposure, and helps new players be able to actually play the game and commit to it after watching a 3 minute video for basics. On the other hand, Rare Devs won't need to create an in-game tutorial because with all honesty, the game has lots of features, it's hard to create an in-game tutorial for a game of this type.
Just my two doubloons, some other games do that, why not Sea of Thieves? :)
