This is DA: Journeys:

It was used to promote DA:O, with DLC available once you did certain things in the flash game. The DLC can be transferred to your EA account, which gives you stuff in the actual game when it released.
It was a nifty little game; kind of like FF Tactics. Took a few hours to beat.
