Just keep an eye on them, most times they don't update and we end up catching em'. Ooh and be prepared to go through my cover project. I'm nearing the end and am going to ask the community to comb through it and find anything I may have missed or messed up on.
I deleted the ones for games which aren't out yet when I realized I fudged.. I submitted a few and then was like... wait a second--Pants let us know that the system picks up on the games once they are released, so if the tile isn't on the site by release day then submit it.
The only one I had left was for a game already out.
