In a bad-vibes moment, they’re denying a huge outlet like IGN a review code. No matter what I think of IGN in particular (nothing good tbh), that’s not something I can find a real explanation for other than “We made DC’s Gollum and want to avoid bad press as long as we can”.
You can’t spell ignorance without IGN.
Unless they’ve published something which is untrue then they still deserve a review code if everyone else gets one.
