[color:"orange"]I guess what I am basically asking is not if it is good, but is it a classic, "must have now" kind of a game? (in its current condition)[/color]
If you have to ask, then I don't think it qualifies as a must have game for you. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
Movement and control is better in the full game, but I'm not sure how much of that was changes in the game and how much was just getting used to BD.
So far I have ignored the BF except for the traders, so that doesn't effect replayability for me. The first act is linear, but starts to open up a bit towards the end with more quests and traders. Since the acts are separate it doesn't reach quite the level of openness DD had, but overall I'd say it is at least as replayable as DD. I have not finished yet, but have made note of a few things I'd like to try differently the next time around.
