Aside from the fact that the microtransactions are promoted way too heavily in EA2D's Dragon Age Legends, I thought it was a pretty enjoyable turn-based RPG for killing time on Facebook (if only I had the time to kill) and unlocking loot in Dragon Age II. But if that sort of thing is too slow for your taste and you're looking for more blood spatters and mouse clicking, then you might want to give the "Remix 01" hack n' slash version a try.
The game is exclusive to IGN for now, but it wouldn't surprise me if it makes its way to Facebook or elsewhere yet if people are enjoying it.
