Just start buying! Unless you already have these lined up it will likely take awhile to source all of those. Say you find an Addams right away, you might not find the 5th game for a few months. At that point you might be done with Addams and answered your own question. Nobody has a forever lineup. you will want to rotate them from time to time.
To answer the question, TZ would be my first to go in that list. Next one is tough, probably Addams Family.
