I haven't even tried 76 yet. I might try it if I can do so for free. I am just not interested in multi. Even with TESO, I played about 45 minutes in toto in open beta. I see 76 as a departure, an experimental branch, more than an indication of future direction. I'm more concerned about how the terrible dialogue choices in FO4 will effect TESVI.
I doubt any of the big Morrowind/Oblivion/Skyrim fans were really very interested in a multi Fallout anyway. However, you can bet your bottom dollar I'll have TESVI at 12:01 release day, and I doubt I'll be alone. Hell I might move east to get it earlier.
