I agree that Bethesda did copy TES formula into Fallout, but it didn't make it any less of a spectacular game. Sure, it wasn't as narrative driven as NV or as well written, but the exploration and intrigue surrounding the Capital Wasteland made it worth it. Still, I prefer Obsidian's version of Narrative above all else, but they could still use a little work on everything else. Bethesda working alone to create the next Fallout like you said will be pretty bad, which is why I'm hoping for a joint union between Obsidian and Bethesda for F4.
