I too believe that the RT, doesn't realy fit in the fallout 1 & 2 environment. I don't mind it in fallout tactics.
I'm a game developer myself, and from a gameplay perspective you either go RT or TB but not both at the same time, It's confusing. And due to the fact that it's a tribute to the original developers interplay & black isle I would keep it TB.
Also because it's actualy based on a lot of gameplay ellements from D&D, and you don't have RT in D&D for a reason.
If I had the time I would try to remake it more like the original one. I do love all the new places and cities they've created it's pritty insain.
