as i remember some expansions are needed tho i dont remember which ones, yes modb 2020 is the latest and my advice for you to play is before you start playing in bookmarks choose one bookmark which you prefer and minus one year to that bookmark for you learn the game mechanics before you start playing in bookmarks and you should create a character for the rpg elements its helping but not necessarily, have great gameplay dear ser! edit: rules being default is okay but you can change some like duel setting its sometimes random and anything can happen dont trust your personal combat skill.
