Well, those are cosmetic, technically, so they would fall under the area that we WOULD be okay with doing. Except that dynamic hats don't really work with this art style, of course. And it wouldn't be microtransaction-based, obviously.
But having, say, a house that belongs only to the character, and which they can customize in some way, might be a thing. Or relationships or pets or something much further down the line. Or something else we've not thought of yet.
Most of that is for well past 1.0, possibly even into expansion territory when you talk about relationships in particular, but I think there are some simpler things that we'll be able to figure out in the meantime.
