on a related note, am i the only one that wishes children wouldn be level 1 when they come of age? it puts them out of kilter with other units in that stage of the game, and questing/monster hunting with them all to get them to the higher levels is such a pain. perhaps there should be some mechanic that gives some of the xp earned by an individual to other members of the faction? so that if you choose to have lots of champions and children then they will all level together, but slightly more slowly?
i would also like to have some sort of incentive not to marry the first available champion that appears. perhaps higher level children from higher level spouses
oh, and also the ability to customize children's starting appearance and stats. too many 16 year olds with beards at the moment. of course, this won't matter too much once the unit-card bug is fixed.
i also think the game could handle every child being a channeler. now that mana is global, multiple channelers should only be of logistical benefit (unlike in the old days, where it really did mean more total power) and mana should be the limitting factor. if that makes having children a no-brainer, then i would argue that staying single should be given it's own benefits. for example, a spell that tranforms the sovereign into an immortal lich but prevents him having children.
