ACG on YouTube I feel does a great job at this if he’s following his publicized guidelines. He doesn’t do any sponsored content nor accept paid for trips from the gaming industry and when he receives a free copy of the game for review purposes he purchases a copy to give away to the audience. Accepting the free early copies and paying to give one away on release seems like a good compromise to ensure he can get the review out near the embargo date.
