Gamestop captured the back of Final Fantasy XIII’s Xbox 360 box, which has bullet points about the game’s features.
Let’s see… it supports one player, saves take up 4MB, and apparently has “game-content download.” Interesting! That sounds like confirmation that Final Fantasy XIII will have some kind of downloadable content. I hope we get something better than Cloud costumes for Lightning and emergency potion packs.

But I do see this coming to the ps3 version as well tbh. It would not be fair for all the ps3 lovers. I hope they will bring in some nice avatar costumes and such. I wonder if they will give us gamerpics for XIII. I want Lightning or even any hot girl in XIII. Jihl for the WIN!!!
