Levels and Emblems

Several years ago, I used Gamespot under different account and took use of the leveling and emblem system. Now there is nowhere this feature in Gamespot.

Is this feature officially retired?

Yes, the feature has been officially retired. If you have any on your account from before the site refresh, they will still show up on your profile, but other than that, for the foreseeable future, these features will not be returning.

For now, it is not something that is being focused on. However, that's not to say that there are not staff members still fighting for the feature (or something similar) to return.
