Dragon Age 2 - Interview @ NowGamer

Dragon Age 2 lead designer Mike Laidlaw has been interviewed at NowGamer in a decent article.  Most of it covers existing ground but here's a snippet on Rivalries, following on from a question on morality:

Can you give us any examples of how this system may be reflected in Dragon Age II?
The Dragon Age games have never been about global decisions, but good decisions. Morality has always been kept deliberately on a grey level, and it’s all about how other people react to the choices you make. So for Dragon Age II, we looked at the other characters in your party and we said to ourselves, ‘you know, it always seems kind of odd that there was a win condition.’

You can be friends with them or they would get pissed off and leave. Now we’ve got a system called ‘rivalry’ in which, in addition to being friends, its now an open choice for you to build up a consistent rivalry with someone and to tell them that no, it’s their moral compass that is not correct and that you can actually have a real interaction around that rather than just them getting angry and storming off. They will still do that, but it’s not like a lose condition like it was in Origins.
