Well, then I hope, they're not getting, what they want.
I have no problem with aging, but, again, what CK2 did great, is the setting pool at the start of the game. Anybody who refers to Crusaders should know, that having an option to choose which features you want to use is crucial part of good experience.
Actually I can't see a problem in choosing in Campaign tab, whether you want or don't to play with aging and inheritance. If you want to feel like in best medieval The Sims game, it's your choice. Nobody should feel forced to play certain type of game, if they actually wouldn't have to.
Albeit, as always, it's up to developers to decide if they want to give us a choice or not. But I hope their pride won't get hurt if somebody could make their own decision.
Giving no choice will make nobody happy.
(maybe except all of those elitist, who like to see the game less accessible and fun for people preferring different playstyles)
