DA2 has much better graphics, obviously. and in my opinion overall is a better game. However in DA2 there is kind of a set location. You can only stay in the city and you can choose for the time of day to be day or night and you can go into mountains. then in DA it is a much larger area, and in DA2 you can only go to/into places if you have a mission/quest there (for some places, not all) where in DA you can wherever as long as you have gone there. Then there is the leveling up system. in DA2 the leveling up system is much more different from the first, the first is a little more, basic? i guess, its not really complicated for DA2 but idk its different. And there are different and more characters in the game and more allies/companions you can have.What are the major differences between the Dragon Age games?
Length.



Origins is much longer.

I found DA:2 to be much more captivating, but way too short. Gotta wait for DLC
