How can i tell if: Games needed partnership to make a video out of

[Calvin Ho]

Just like above, how can we actually tell? Read wikipedia or something?

Games never need a partnership to be posted onto YouTube?

Usually when you buy a game it should come with the license conditions. Otherwise they are stated on the publishers website. If the publisher does not explicitly state you may broadcast the content (commercially) world-wide you need to ask them for such a written and signed broadcast permission. In case you can't get such a permission you would need to partner with a network that has it.
