I hope you are right and it is indeed easy, but I'm afraid it is a core mechanic built in the game. You see, every single AI character in the campaign is subject to dying and being replaced, if I understood correctly, so probably "turning it off" is not as simple as one could think.
What could be simpler, however, is deactivating the feature for the single PC via a sort of a "cheat" line inserted somewhere in the script (I don't really know it's mere speculation), which could be invisible in game or even a modded in trait the player can acquire
No, unfortunately it's not really easy to turn off aging at the moment, according to what Callum answered on the modding thread I have mentioned previously in this thread. But this is subject to change, so there's hope.
My problem with aging is, it doesn't really suit in a game with a time span this short. Comparatively, it's
much shorter than CK2 or Total War. We don't have several features that are present in the aforementioned games precisely for this reason. A few examples:
1) Culture won't change if a settlement is taken by another faction, no matter for how long they 're gonna hold it for
2) We won't have any technological advances over time. No plate armours, halberds or arquebuses will kick in after some time, implying that the focus of the game is centered at that limited period of time
3)Even though we do have sieges and are technically able to starve a settlement instead of assaulting it, I never see this feature being put into use. It takes less than a week to reach anywhere on the map, so assuming there is a rescue force coming to help, chances are it's gonna be there to break the siege. Although I believe this could be somewhat easily fixed by considerably reducing the granary storage and/or increase food consumption
There's also the issue with the rate characters will be dying. It will probably be challenging to keep up the replacements with the following generations. Will we have regents? I doubt
That said...I don't know about you all, but I like to play mainly historical/fantasy mods, where there's a storyline and the specific characters of that time in history/fantasy lore. I find very enjoyable to play in a world populated with all those characters I am familiar with; but not much with the following generations, as they're all random and not part of the lore. It will be amazing to play a LOTR mod and battle side by Faramir, Gimli and others, but if they are all dead, I see no point to carry on. Ironically, I don't care if my character would eventually die, because I am the player, more like an observant who is not originally part of lore - even if I will be the character who will most actively shape the world.
I will definitely try the aging/heir/death system during my vanilla play as soon as I can. A lot of effort is being put into creating a solid lore into Bannerlord, but we're not quite there yet, so I don't really care much about the characters.
