No replayability? Are you serious? It was good for several playthroughs and more. Maybe it had no replayability for you but the general census was that it's generally a very replayable game if you enjoyed it.
The sequel on the other-hand wasn't very replyable due to lacking customization, no true consequences to choices and limited class customization with weapons specific to each class. Origins allowed you to create a dual wielding warrior, sword and shield warrior or two handed weapon warrior and you could even give them a bow and level them up in archery skills. DA2 on the other-hand only allowed you to create a sword/shield and two handed weapon warrior and the specifications didn't really add diversity, they were just extra skills.
Origins only starts lacking in replayability when you run out of ideas for class builds and go through every Origin having made every choice there is to make in different playthroughs.
