Not seeing Ready Player One listed here. There were some choices made in that movie that might seem fine to someone who hasn't read the book, but the huge number of absolutely unnecessary discrepancies was just gross.

That doesn't excuse swapping Wade's deliberate-servitude-to-hack-the-system with Art3mis's damsel-in-distress-happening-to-save-the-day-by-chance sequence, nor Wade's decision at the end to shut off the Oasis two days of the week (what about people who rely on the Oasis for their livelihood or for self-worth, like severely disabled people? Hello), nor him saying his friends are his "clan," something they are vehemently against in the book.
