I have, and it was totally obvious he was entirely genuine in his response.I think you lack the ability to tell if someone is being diplomatic due to professionalism. I also wonder if you actually watched the interview you are so fond of quoting.
Just to be clear. I think he did like it in some ways (most of us do like some parts) but you can clearly tell he wanted to say more but couldn't.
The idea that he couldn't say more when, at the time, he wasn't working for Bethesda, Obsidian, or anyone related to them, and had no plans at the time to leave his job, and was thus totally able to say anything he wanted with zero consequence, is literally a fantasy. Game devs shit talk each other all the time, if Tim really hated it, he veyr easily could have said so with no negative result coming from it.
Its this sort of conspiracy mongering that makes NMA so infamous.
