I'm honestly not trying to be nitpicky here, for what it's worth. But, just in case it matters to anyone, I believe it was said that you'll still go to/use the stronghold even if you don't "do the stronghold management," but you won't necessarily own and neglect it, I don't think. In other words, I don't think you're forced to take responsibility for the stronghold, and have your only "opt out" option be "I'll just neglect everyone after taking direct responsibility for the well-being of this place."
It seems relevant, since the reputation system would either have to factor that in (so your "no stronghold" option would really be "have everyone hate you for not-taking care of your stronghold that you can never not-own"), or very arbitrarily leave it out.
You may HAVE to own the house there... I'm not sure. But, I think the stronghold will simply be your party's sort of safehouse/base-of-operations, whether you own the whole thing or not. Almost like a home city. You live in and are a member of a community in your home city/town/whathaveyou, but that doesn't mean you own/rule the entire community.
So, I think maybe the only think you can't choose to do is to be un-welcome there. Who knows... maybe you CAN choose that somehow? *shrug*
why would there be a community surrounding an un occupied stronghold though? seems odd, they wouldn't have any taxes to pay/ any law to follow etc if no one rules over them. im wondering if the community starts if you chose to own the stronghold fulltime i.e you gain ownership, start doing it up then people start to inhibit the surrounding area. otherwise anyone living in that area before hand would just be squatting, maybe?
also forcing the player to own something they may not want to is not giving us freedom of choice. im sure there will be suitible alternatives to this and not just "you have to own this, but if you dont want to you can piss off and neglect it, but its still yours". i was just curious as to what they may be, though as i said above will most likley be "do or don't", either own it or dont own it, your choice.
owning a stronghold does sound really indepth and fun, but not something i would want to spend time on first playthrough. fisrt play is for full exploration, second play the immersion of exploration will be dulled a bit (been there, seen that) and owning a stronghold will add new experience to the game. so its a great well thought out addition to the game, i was just curious as to what the alternative to owning it may be, because "its yours to neglect" is a bit dull.
