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”.
Reviewers getting copies a week before launch are generally netting like 40-50 hours of game time in a short timeframe. Combine that with the fact that it’d be more like hundreds of reviewers and you might actually have a decently active community.
