I've always been a fan of party based RPGs, so DA:O get a free bonus from me for that. Bottom line is though that DA:O is a much more polished product than Divinity II. While DII shows signs of brilliance here and there, there are so many small issues that irritated me to no end:

- Getting stuck on almost all of the crap that litters each area
- Endless barrels, boxes, baskets, urns to smash up (after you figure out you don't have to open them all individually), with lots of them located out of reach (upper plank, must contain sweets eh?)
- Confirmation dialog for a -successful- load (I like to take that for granted, thank you very much)
- Cannot quick load while you're in the process of dying
- Ugly saved games screen
- Where can I find the saved games in the directory structure so I can easily delete excess files?
- Hints suggest from the very start of the game that you have access to your Battle Tower and "assistents". This takes 50% of the game.
- Inconsistent difficulty, difference in levels between you and your targets has a "magic" effect on damage dealt
- Seems to me lots of skills and effects are pointless
- Numerical increases of skill related values is completely wild

I could probably go on and on. Perhaps only inconsistent difficulty is a truly serious issue. In any case DA:O is definitely 'slick' compared to this.
