It'll be interesting to see what happens, and if these ethics policy changes really make any difference. Even apart from what GamerGate brought into focus, games journalism has suffered an increasingly bad problem with credibility for a long time now. I think someone at IGN must realise that if nothing else, they have a bit of a PR problem that needs some work. Hopefully it's not just a PR solution as that wouldn't really do anything other than being a short-term fix.
