Oh, I also have the online DA-Legends game downloaded to my PC (used to be a available exclusively on Facebook), and the mobile game Heroes of DA (on iPhone, along with the ME games).
Only one I don't have is Dragon Age - Journeys: The Deep Roads, since it was a browser only game that they never released for download to play on your PC after the website that hosted the game went offline sometime after Origins release. I did get to play through it, luckily (it gave you a few free weapons in Origins if you linked it to your EA Origin account).
