DA:O actually had too much dialogue, in my opinion.

I don't mind games with lots of text, (I loved Torment, for example), but, because Dragon Age insisted on using the 'cinematic presentation' for every single dialogue, AND voiced it all, dialogue very quickly became tedious. I did not care for ME1's dialogue system either, (the fact that I don't know what exactly my character is going to say), but I'm glad the sequel has less dialogue than DA.
