Paul has talked about how IA races will be controlled by attributes, one of them being how aggressively expansionist they are. Thus GC2 minors are not at all expansionist, GC1 minors were just as aggressively expansionist as majors. What everyone is arguing for here is the ability to set the level of expansionism for minors. I would love that option.
Having the option to have minors not expand in one game, timidly expand in another and aggressively expand in a third seems like a great feature. Best of all everyone is happy and can play the way that want.
