What happens if you keep playing the vanilla game without the expansions?

Dont have that info other than I was told that the game really is designed with the expanded content in mind. The expansions for this game will hit often and they will be very large so you would be missing a ton of content.

Well they said from the beginning it was a 10 year project so I'm guessing you can't reach the end without it.
