My main problem with Set 1 is that it felt incomplete. Where were the rules for playing a Grey Warden? How about a Dwarf? Heck, how about a description of Orzammar? Where are the Qunari? A lot of the spells I liked from the video game weren't in there. There weren't a whole lot of monsters in there...just the basics, which to be fair was the stated purpose of Set 1 but left it feeling incomplete. Set 2 goes a long ways towards fixing those issues.
A good friend of mine, and regular commenter on this site as Game Hermit, picked up Green Ronin's Dragon Age RPG, based on the very popular Bioware PC game.
Bioware and other assorted involved parties have just announced the first official expansion (read: bigger than DLC) for Dragon Age: Origins. DAO - Awakening! There's not much on the official site as of yet so here's all the info I've got my hands on so far.
