Played both on 360 and PC.
6~ playthroughs on 360.
1 on PC.
I've encountered quite a few graphical bugs and sound problems which I really do hope don't carry over to the main game, for example; talking to a companion and then talking to another will have no audio from the second companion but their lips move and you can see the subtitles above their head.
The exaggerated portion was loads more fun on the 360 as a whole, rampaging through everything was a lot more fun to me personally. Though once we enter real time, I found the PC version provided a lot more in terms of fun. Though it did leave me a bit confused as I found the game to be a lot easier on PC even when I was doing nothing different which was rather... odd, my companions were able to kill everything without dying on the PC while on the console I'd often have to keep close tabs on every one of them.
I've tried to play around with companions on the PC playthrough to get a different feel, I'm really interested in how the game feels different for both but remains true to both platforms. I didn't have much fun with 2h warriors on the console, though a 2h warrior on the PC played a lot better. Opposite (personally) for sword and shield on the console.
As a whole, the demo was loads of fun and the textures on the console compare to my PC which is some good news. I'm sure DX11 would change that but I don't expect it by too much. Though I've seen a few bits of clipping on the console which I don't believe I saw on the PC, like Flemeth's head in which you can see the neck stick out of the armor when she turned her head.
Voicework wise, both FemHawke and ManHawke did amazing jobs and I loved every single line except for one which struck me as a little blunt (The line where they dead sibling will keep father company). Personally loved the moment where Flemeth laughs and says she likes you.
I'd write a few more things but I'm in a rush, so... can't wait for March 8th.
