I consider myself a fan of Fallout, at any rate I did before, and I was grieved to see it ransacked at the hands of an increasingly desperate Interplay. But it's become clear that what makes it Fallout to me is very different than it is for other fans. We ran into the same issue with Tribal War over Tribes 2, culminating in a brutal conflict that pitted gamer against gamer. As it relates to Fallout, I am distinguished from what you might call the Orthodox fan of the series. One is that I simply believe that elements like Turn-Based and Isometric were artifacts of their time. There is nothing wrong with them mechanically, they do not want for elegance, and the genre is still going strong in Japanese titles that I play and enjoy. But I'm not going to create a religion out of it because tiled environments happened to be expedient a million fucking years ago.
Fallout is not - for me - defined by its perspective. It's defined by the unique setting, and the meaningful, satisfying choices I can make to affect that setting. I don't care where the camera is. If those things are intact, they can put the camera in geosynchronous Goddamn orbit.
