Hi guys,
i have two simple questions…
A: Is it officially alowed to post Videos on Youtube?
(Maybe some Tutorial stuff or Videos of Clanwars, Cups, Unreal Engine Footage etc.)
B: Is it officially allowed to monetize such Videos on Youtube?
Thanks 
Pretty sure I remember reading about similar topic on the AnswerHub.
Take a look there, see what comes up.
I’m pretty sure you’re fine if its your content, your tutorials etc.
You can post and make your own videos and make money off them without paying any royalty.
