I was searching around trying to find info on why the IGN app seems to be unlisted in the WP store, I found no reason, I instead found this on IGN's site:
fix the windows phone 7 app
It's from last year but I think they still look at this for suggestion (like MS does with the same uservoice thing) and even though it's marked as planned, I think it is taking way too long. So if you want them to take WP more seriously, as far as their app is concerned vote for it. Besides their app was good when it worked. It would be great if it was updated with more features such as pinning and what not.
