This was a very famous sticking point for the Madden himself, refusing to attach his name to anything that didn't have eleven guys on each side. This actually led to them holding up the first edition for three years. No question someone else would've come along with this eventually but as we mentioned before people played videogames in the late eighties too and it became a statement that while other titles had their place in the market Madden was the series striving for authenticity.
