I guess your reading comprehension is off this thread is about system sellers which MLB The Show isn't and never will be.

What is a system seller?

I don't want examples, I want a definition.  

A franchise that consisently sells over a million units on a single console when it comes to sports games there are only three Madden, NBA 2K and FIFA.

why is the million seller condition just constrained to sport games? shouldnt all system sellers be able to move one million units of software?
