I enjoyed some of the DLC for Mass Effect 2 and Dragon Age
Specifically Lair of the Shadow Broker and Witch hunt. But that was about it.
Leliana's Song was good too. But most of them were much too short, especially in the case of "whoopy doo, a new item" as was too often the case. Rather sad to see that sort of thing is still being practised as I don't recall too many people saying "we must have more content like Horse Armour!" back in the day, for instance.
But even considering some of the better DLC, I prefer to see proper full-size expansions rather than dribs and drabs that tend to be DLC's hallmark, things like the Shivering Isles for Oblivion and Bloodmoon for Morrowind. And, indeed, Flames of Vengeance. And it's not just the value for money element when it comes to micro-DLC (or rather the lack thereof) but that it sucks that just as you're getting into it, that's it, it's over.
