RDR seems to be fake due to the missing banner and being out of order related to the other games, since they're sorted by size. Tekken is definitely fake though. The pic was taken from the achievements screen, which shows all XBOne and XBOX360 achievements for games you have played.
Games will show their size in descending order if you sort by size instead of alphabetical order. But the RDR one is out or order so it's definitely fake.That and the missing XBOX360 banner on the side give it away.
Do it. You won't be disappointed.
