That house thing is less interesting to me than anything. I don't even bother with crafting in games, if I can avoid it, and for some reason it makes me think of crafting.
If it's a narrative device rather than a sandbox to play in, that's different! But if I'm going to be collecting wood to build additions, yuck.
I guess I've never played BG2 long enough to experience the stronghold portions… so I guess I dunno what they have in mind.
