I am reserving judgement until the end of the game. No doubt it is a good game, certainly huge in scope, better than DAII or ME3, but I am still not sure it measures up to the classic Bioware RPGs and even more recent ones such as KOTOR, DAO, and NWN I and II. There are just enough annoyances in gameplay and PC controls to keep me from unqualified enthusiasm. Mainly, the removal of healing spells, limited hotbar slots, terrible PC controls, and a story that just seems to get lost in all the different regions and sidequests. Edit: none of the new characters really strike me as particularly interesting either. As a matter of fact, I have caught myself wishing Lilleana and Morrigan were playable. They seemed to have much more character than the new ones.
So I am waiting to see how the ending plays out, but definitely a very good game, not sure in my mind if it is great or epic yet.
