No it's not unfinished, at least for the PC. It's just the full game comes with Dwhatever 11 and the demo only runs on 9. So it can't go up to par unless they include that upgrade, and that would have been silly to add that just for the demo. I think the reason it was so massive was the cutscenes and the actual quality of the fights. They were much more involved than ME or DAO. Or so I thought.

You can still turn on the a to attack and they do it on their own feature. By the way vyk. So if you don't want to button mash then you can just go back to the boring swing when they feel like mode. I personally like things to attack when I tell them to attack. So I have NO problem with the change

I linked it before but I'll do so again. It'll appear on this page http://social.bioware.com/user_entitlements.php. For the item you get.
