I just wondered if you can have more than eight sims in a household without downloading a mod, like NRAAS?
I mean, can I create a tuning mod that increases household members?
If so, where can I find the XML(I assume?)for the household size?
I don´t think the XML I´m talking about even exist in Gameplaydata, but you never know...

Thank you.

Offhand I would have to say probably not. This isn't a very scientific answer, but if such were reachable by tuning then we wouldn't have to provide the options within five different script mods (MC/MC Integration, SP, Woohooer, Mover) to cover the various ways that a player might want to allow for Greater Than Eight and then a sixth one, PortraitPanel, to make the overstuffed households more playable. Honestly, it's not set up that way just to be annoying.

Then of course there's the Awesome core mod all-or-nothing approach, less customizable to the player but probably at least as complex under the hood.
