YouTube gaming commentator Total Biscuit does not like used games. He's no suit defending The Man. He's a hardcore PC gamer and man of the people.
Now, he's not right about everything (to wit: he thinks we're "terrible"... yeah, ok). But he makes some great points about used games being no-good.
Got half an hour? Give his argument a listen. He's considering many points of view.
Used games might be a convenient industry scapegoat, but that doesn't mean they're not problematic. The man makes a compelling case. Feel free to disagree. There are strong arguments for and against.
