Dragon Age was a very good WRPG, but in my opinion it also was Bioware's worst game to date (yeah, ok, maybe it was a bit better than the Baldur's Gate 1, but that's a meaningless comparison). It also featured some of the worst value for money DLC to ever appear in the gaming industry. For me, while the game was playable and enjoyable, it also felt "factory-made", like the immediate product of a strict and restrictive set of game development rules rather than the product of passion and inspiration. It was also not mod-friendly, which dramatically reduced its value.
For the sequel, I would love to see Bioware break free from their self-inflicted restrictions. I'd like to see them spice up their "standard fantasy setting" a bit and attempt to catch us off-guard. I can't think of a moment in DA where I went "Wow, this is awesome, how did they think of that?", which is something that I thought multiple times during Demon's Souls for example, and that's strange since DA can be a much deeper game than DS. I'd also like to see more original character design, since their usual stock characters, although high quality, have become a bit repetitive. I'd finally like to see them try more to support free user-made content and create a powerful, user-friendly editor that will attract independent artists and their ideas. In my Neverwinter Nights game box I have a separate cd-case with 2 DVD-R's full of user made campaigns of STELLAR quality. I want this kind of community back, and I want Bioware to actively pursue this rather than putting out 3 hour DLC's for 15$. Don't you dare disappear into the dark side, Bioware. We need you.
