I have all the games on that list as you with the exception of IM. I know GB has alot of varying opinions. I really enjoy it and would miss it if I didnt have one. GB is a case where the pro plays better than the premium/LE as well. If I were you, Id move IM along. Im not a fan of the music and the theme does nothing for me. There always seems to be IM for sale so, if it is missed you can pick up another one easy enough.
