Gaming tutorials?

I got an idea for a start-up today and I wanted to ask you for your opinion:

Personally, I sometimes like to have tutorials for certain games like Fortnite or WoW, which explain to me exactly how to play best in order to be successful and to win. For this reason, I would like to set up a platform and create "instructions" and tips together with experienced players, giving gamers the opportunity to improve their game significantly.

What do you think about the idea? Would you watch such videos?

A good idea in itself but I don't know if such a platform really helps if you can already watch thousands of videos about every game on youtube

I think you can find almost everything about every game on Reddit and YouTube
