Gothfather: I gave a solicited opinion aka I was asked so I answered. What? I have to agree with people for it to be valid?
No, you don't and I never said your opinion is wrong or attacked it. By means of discussion we come to a greater understanding of ourselves - but there's no discussion without opposition, don't you think? And.. Well, why even post on discussion boards if discussion is not what you want?
Anyway, to start off with facts: No, Obsidian is not swimming in money. All of their previous projects were funded by a publisher, which means they were paying Obsidian to develop a game and then took most of the profit from sales. Pillars of Eternity was the first project Obsidian tried to achieve without publisher money and so they raised about 4 million via kickstarter. For comparison, the original BG cost over 4 million dollars, BG2 over 5 million dollars, and that was 15 years ago. To put that into perspective, Mass Effect 3 cost over 200 million dollars - suffice to say that the modern technological tools are rather expensive to fully implement, and you wouldn't believe how expensive voice acting is. So yes, Obsidian did need the money from communuty to make the game possible and they have actually funded part of its development from the limited funds they have aquired trough the years. The kickstarter vs. preorder discussion is completely irrelevant, so let's just not go there.
As for your given example of voice acting being implemented poorly - you are correct, but that is not dated design, that is bad design. The fact that VA skipped lenghty descriptions and made you read the whole thing, anyway. Personally I would prefer Obsidian to skip voice acting entirely in such a text-heavy game. Why did they not do a full voice acting is something I have answered already - voice actors are really, really expensive. Ridiculously so. Then again, that doesn't really answer much - you say they did not use modern tools and design advancaments, but I still don't understand full extent of these, I mean surely it's not just poor voice acting.
All right, now, our misunderstanding might quite simply come from different expectations, so let me ask you a question: How many low budget RPGs have you played recently?
It still feels bizarre that you would fault Obsidian for doing what they very clearly stated they'll do, like saying that you bought a bike and hated it for being a terrible boat. Then again, I guess it's a perfectly valid reason to dislike a game, I mean I dislike sports games for being sports games.
