No on number 3. Leave the Enclave dead and buried where they belong.
yeah idk how hard it would be to make New York as the main location for the next chapter with all the tall buildings but would definitely be possible, but I figured New Jersey/Pennsylvania (both as the major location) would be a nice place while being a little easier to make while also having the close connection to New York whether that be dlc or not. But I feel Pennsylvania would definitely be worthy historical wise(also since they possibly already had an idea of what the PA situation was to be like) and I would really like for an Always Sunny cameo type of thing...hehe..
I think they should add a game that takes place on October 23, when the bomb fell. You would somehow survive and have to escort your family to safety. It wouldn't be a huge game, just like DLC sized. You can see the military in their power armor and maybe even experience parenting in the wasteland, which would be a different take on the series. I'm new here so I'm sorry if I make mistakes or something.
