Trust me. I saw it first hand since DOA5 was my first DOA game. The 10+ characters DOA5 added during its run didn't change anything and nothing DOA does will change that anytime soon. That's why it was logical TN added Marie and the rest. If the neighbors, as you put it, don't care about the game then TN might as well cater to the people who actually play the game. Like Diego for US and Nico for Japan.
