I'll repost what I think here for the console version of DA2. I'll post some PC feedback later:
"The demo on the console reminded me a lot to Jade Empire. The portraits to the bottom left with the mana/stamina look similar, the constant tapping of (A) and the radial menu are somewhat similar. The gameplay felt smooth and very cool looking, with the running and slashing. Combat was, personally, a little too fast for me. I wasn't sure what was happening some times, being unable to keep up (which led to some of my companions "dying" as I couldn't watch their health, pick a skill/ability to use and tap A constantly). This is more a personal problem for the console version though, as the PC has the "pause-and-command" style, which I will be using instead. Overall combat was fun to watch, but difficult to manage (for me any way).
Regarding dialogue, I was little confused by some of the symbols/icons when choosing your dialogue. For example, what does the purple diamond represent? And what's the difference between the olive and the wings? The paraphrasing was usually fine. I raised my eyebrow at certain things Hawke said, but I didn't mind too much. The voice acting was fine by me, and I liked the "sarcastic" comments the most. Regardless of what dialogue option and sex you initially choose, Hawke will sound like a badass, which was awesome. I was ecstatic watching Flemeth arrive in Dragon form, and the little story I saw I thoroughly enjoyed. Seeing and hearing Varric retell the story of Hawke was great and I felt it was quite a fresh and original way of storytelling.
I like the art. The loading screens were cool, and the music was well done. I enjoyed hearing the title screen and credits music, though the in-game music was less noticeable for me. The graphics are greatly improved, with mostly sharp textures and fluid animations (only things I didn't like were how the darkspawn looked like and some minor instances of low texture resolution, especially visible in the very first cutscene where Varric is dragged into the interrogation room). There were some minor glitches. For example, I chose to wield a sword and a shield, but whenever I was in-combat the sword would be held upside down. Occasionally some textures would glitch and turn white.
It was fun, and I'm eagerly waiting for Dragon Age 2. I can't say I enjoyed more than Dragon Age: Origins, but I have yet to play the full game so there are probably a few more surprises in store for me."
