Dragon Age 2 - Previews @ Strategy Gamers, IncGamers

A standard Gamescom preview of Dragon Age 2 at Strategy Informer:

Most of the other improvements we noticed were related in some way to these core three concepts. The dialogue wheel has been tweaked so that it now carries emotional sub-text with the choices. Silverman quoted the popular saying that Email is a poor form of communication due to the fact that you can't read emotions, and he has a point. You don't really know the effect of some of the options (unless they're really obvious) until after the fact. Now, this 'emotional' wheel gives hints in the form of icons that are supposed to represent emotions, or stances, or something that really helps you see what the choice is meant to achieve. A small touch, but one that we think will make the cinematic experience that much more engaging.

...and another at IncGamers:

Conversations, too, are improved over the first game, but as with everything else there's going to be a bit of an uproar from the old-school. The conversation system has shifted from complete sentences to Mass Effect 2's dial system, although here, different coloured symbols dictate whether a response is friendly, neutral, or aggressive. They're even organised the same way, with the upper options being the most good-natured, while the bottom options are the harshest. As we're now dealing with a single possible main character we also get all the other benefits of a world that contains Mass Effect 2, like full voice acting and animation in conversations that ranges from lip-synching through to smaller details like snarling, shrugging, and raised eyebrows. It's a hell of a lot more immersive than the mute puppet that was Origins' Warden.
