I'm about to start making a video game guide to sell on Clickbank and curious to hear your experiences. I know the default-legally-correct answer is to "consult a legal adviser". Done that and he said, because it's for teaching purposes, according to fair use it's okay. Even so, I hear others say it isn't okay leaving me confused with what to do.
A plethora of game guides have been created on Clickbank using in-game content: https://www.clickbank.com/mkplSearch...atFromNav=true
