The last DLC I got was the one my boyfriend got me on my Xbox360. The DLC was "The Passing" for Left4Dead2. It's enjoyable and we both had fun playing it together.
Some count skins on League of Legends as DLCs. (It's extra content that you have to pay for...but it's not 'downloadable', just unlocked)
If you do, I just got the Pentakill skin for Sona today.
I bought all of the DLC for Fruit Ninja. I should actually say that Microsoft paid for the DLC because I had just gotten my points from the Triple Play promotion. Gotta love XBox Rewards, they save me so much money. I have point cards sitting waiting to be redeemed, but I keep getting points, so they keep sitting.
