It looks like Snowy Escapes is bringing a personality overhaul!

I'll hold out first. Most likely, they'll just manifest as optional talking options, moodlet modifiers or throwing in a few idle animations. If they work at all, and aren't bugged to high heavens.

If they patch this into the base game, I'd be more positive. That would show that they want to continue developing the mechanic outside of this pack and keep working on it.
