Final Fantasy XIII-2 DLC, with all twenty-plus items on sale on the Xbox Live Marketplace and PlayStation Network. True, most of the premium downloadables feature weapons and outfits (though what outfits they are), but there are discounted options for those who focus on the 'content' side of downloadable content.
'Lightning: Requiem of the Goddess' is 50 percent off at 200 MSP/$2.49 on XBLM and PSN. Within is an episode which sees you play out Lightning's story in a battle with Caius, before unlocking the heroine of Final Fantasy XIII as a party member. Also going at half-off is 'Sazh: Heads or Tails' for the same price, and Snow: Perpetual Battlefield at 160 MSP/$1.99. Both unlock the named heroes for use in the sequel.
The sale doesn't end for another week, so there's plenty of time for you to... what's that? You just want to see Serah in N7 armor? Well, fine, you go do that.
