probably the single greatest western RPG of the last decade, with only a few others able to come close to what I consider perfection. It's such a shame that Dragon Age 2 and Inquisition wasn't able to live up to Origins... I had such high hopes for both as well.
Origins was just good in everything it did and was almost like a perfect combination of micromanaging party combat system, superb and interesting characters, really strong world building and lore, and RPG stat/class and equipment building.
Dragon Age: Origins is great, but I guess I'm one of the rare kind that always liked the other two parts a lot as well. (As my sig probably shows.)
I will admit that the 2nd part was definetely the weakest, it felt very rushed, the writing wasn't nearly as good as in Origins and the story was all over the place, especially in the first half of the game. I still had a lot of fun playing it, and the gameplay felt a lot smoother than the clunky combat of Origins. I also really, really liked Inquisition (played it like 3 times already...) My only critcism would be that they tried a bit too hard to be skyrim-ish. They could have scrapped some of the open-world-regions in favor for more story content. Or heck, just more stuff with your companions, because that was probably the strongest part of the game.
