There has been a lot of talk about Dragon Age 2 and if it lives up to the legacy of Origins. I can tell you now that it is a very enjoyable game that is compelling and fits well into the lore. That said, Dragon Age 2 is a totally different game. While I definitely like parts of it, there is something missing. There are lots of places where the game feels cheap, like Bioware didn't have the budget (or care to allocate the funds) to really flesh the game out. I think people would be much happier if the game was called "Dragon Age: Hawke's Quest" or something instead of being labeled as a full numbered sequel.
A big plus for it though is that I am playing on Xbox 360 and the game is much more playable than the first. I would go so far as to call this the defacto Dragon Age game for consoles. It feel a lot like Mass Effect 2.
