They range from weird to potentially sensual to the ostentatious.
Let's start with the weird. Amazon's giving away the "Omega Boss Battle" pack, an exclusive "coliseum battle" that adds Omega to your party upon completion. Sure, ok.
Then there's the potentially sensual. GameStop has a new costume for total jailbait Serah. Errr, yeah.
Then there's the ostentatious. Best-Buy is bundling a hard-cover book with pre-orders, featuring "Final Fantasy XIII Episode I", a novella connecting the stories of FFXIII and FFXIII-2.
Pick and choose.
