Thanks for the link OP, it was an interesting interview and raises some questions for me.
"There are some things I think that are certainly fair criticisms: the re-use of the levels is something we knew was a bit of a risk, but we wanted to make sure there was more content rather than less, so re-using some of the spaces and coming to them again was certainly one we were careful about and tried to re-use as artfully as we could. "
-Reusing areas to increase content? That seems like something of a contradictory statement. He may of meant they tried not to reuse content but alot of reviews out there mention the reuse of alot of content.
"Well it's hard to know exactly what's going on with scores that are really, really negative. One possible culprit could just be a change backlash, i.e. this isn't Origins and I wanted Origins 2. There may be some degree of what I would honestly say is emotional investment in the Origins story, or in the way Origins was presented which is leading to a stronger than average reaction of disappointment. That's understandable, and if anything that really is a compliment to the work on Origins."
-Wow, that comes across as a bit egotistical. Gamers don't like DA 2 because DA:O was THAT good? DA:O was a fun game, to me, but it was far from perfect.
"Dragon Age II was designed by just the senior, core team. Honestly I don't feel it's a game that's been designed to appeal far and wide and so on. If it were, there were choices we could have made that would have taken it much, much further. We would have probably simplified down to a single character, maybe with companions; probably looked at doing some even deeper changes to inventory management, making sure that... You wouldn't want to confuse people with enchanting or anything complex like that."
-Wasn't there a press release about six months back about trying to capture a wider audience from other genres? I remember the mention of CoD fans as an example. Has this position been reversed somehow since release?
"I would say get rid of the idea it will be a re-hash. Getting rid of Baldur's Gate is a terrible idea, it created some really fundamental elements of what we've done with Dragon Age: Origins and Dragon Age II. It's never going to be the same game every time out. We see Dragon Age as a story about a place and a time, not just a singular story that continues through games."
-But the promotions on the forums did promote DA:O as a spiritual successor to the BG series. Hopefully this means that if there is a DA 3, it will not be about Hawke!

The interview is, of course, longer than that but those were the curious parts which stood out to me. Overall I thought it was a good interview and I'm not trying to be rude or harsh on Mr. Laidlaw or Bioware. DA 2 is a casual mystery to me and I'm curious about how it came to be the product that it is.
