The problem is there is ALSO large group of CivFanatics who DO have the game now and DO like it, who will be pissed if design resource start being spent on making it completely different game than the one they like.
But somehow, mysteriously, the people boycotting the game *now* seem to think that only THEIR opinions will ever impact sales, and that it's therefore okay to piss off the people who like the game right now, because they obviously have no standards and will continue buying the game and expansion anyway.
Thus they keep insisting that no, the only way to fix the game is to make it exactly to their standard, centered only on their need, and without any compromise for the people who like the game now.
