Xbox LIVE’s Games on Demand service is really beefing up with all kinds of excellent titles these past few months, and now we have two new additions to the family.

In most parts of the world, you’ll be able to buy and download the great open-world action game, Crackdown (check for your region’s pricing over here), and if you’re in Japan, you’ll be able to get Beautiful Katamari for 2000 MS Points.

If you need a bit of a refresher course on these games, you can head on down below to see original trailers for both Crackdown and Beautiful Katamari, to remember the good times:
