Do you need an account to play? Or would I be able to just run the game without any internet access?
I am assuming I need an account because the description asks for you to redeem a key
You will be able to play offline just fine, all you gotta do is login on first game start once
so it is required to have an internet connection.
System requirements on vintage story website say that "Internet Connection required when starting the game for the first time". After you do it you won't need internet connection anymore.
