Oh, wow, I forgot that in addition to Dissidia 012 today, Tomb Raider Trilogy Pack was also released today, which also counts for the site. Just a heads-up for those who are looking for more codes to redeem.
Edit: Oh yay. It's saying the Dissidia 012 code can't be confirmed, like w/ Tactics Ogre. Well, guess I'll try again tomorrow.
3/23: Um, what? So I finally got the site to recognize the code Dissidia 012 came with &.....it's telling me it's for Tomb Raider Trilogy. WTF. Well, I know someone else who'll be getting the game, so I hope it just happened to my copy. Least I've hit Ultimate Tier. Now if Square Enix could just announce the prizes....
