I've been suffering from both culling and relationship culling since day one. It's old news, but I'll rear my ugly head to support your cause because I believe in it. It's the most belligerent, arrogant, hostile, and ignorant idea Maxis has ever come up with and it's completely unnecessary unless their engine is completely incapable of handling anything beyond that. In which case, they blatantly lied to us. Which again, is belligerent, arrogant, hostile, and ignorant to the players.
