I had the same questions when buying. I went w gb. Glad I did. New code coming. Munsters too easy. Premium version not good. I like mb...a lot. But where will you be in a few months with it? Shallow, old game. Read how many people on here blew threw it.
Now, gb, it's generally a harder game. For me, it makes me a better pkayer. If the gb code updates is a game changer like game of thrones was, then u really have something special.
