[quote name='Solder']Pretty sure it's a single code that once redeemed gives you a list of codes for all of the individual items.[/QUOTE]
For the PS3 version, it's a single code that has everything (costumes, avatars, and the games).
I'm not a hardcore fighting game fanatic like I was back in high school and college, but I'm still having fun with SFxT.
I definitely could've waited to buy this edition and saved myself $50, but silly me thought that these would actually go quicker than they actually did/are.
I based my assumption that the same # of copies (30k between the 360 and PS3 versions) were the same as the EU MGS HD Collection LE, but the SF series has a larger and (arguably more) dedicated fanbase than the MG(S) series.
