"For Fallout 3 we did five DLCs. That was a very aggressive path for us. Our plan now is to take more time, to have more meat on them [for Skyrim]. They’ll feel closer to an expansion pack. With Fallout 3, it was, ‘Ten dollars is the sweet spot for us and we know we want to put out five of them. And we had overlapping teams. We were coming off Fallout 3 and right back in. We just think we can do better content if we approach it a different way."
The Small DLC's that you were on about, were to be free to tide us between larger DLC's (aka the free stuff we've been getting in patches)
To be fair, that quote doesn't actually say they wouldn't put out small add-on DLC, only that they want to focus on making DLC that feels more like full expansions, it doesn't actually preclude the possibility of other DLC if they feel it is worthwhile. The free stuff we've been getting has been substantial, and for me is a great sign that Bethesda truly want to support the game and the fans after the games release, not just going for the money, however, they haven't really been significant gameplay and content additions, just some new stuff to expand on what is already available. Not to take anything away from it, the stuff has been great, but it's not hard content that could really be given a value, this is, and to me, it really is worth it, and in truth, something I was hoping they would do, adding good new hard content in little add-on packs in between full DLC releases.
Of course the worth of a thing is down to the individual and I could totally understand why someone wouldn't think ti was worth it. Whilst I would love to see something like the idea the OP suggested (as I've said in another thread, I love the idea of a settlement being built in the same way), this house add-on clearly adds a lot of gameplay and is worth, to me, the very small price.
