Ya know, I was just thinking...wouldn't it be super cool if we could upgrade our houses? Like, spend 20k to put in a second story. Or spend 10k to put in an animal pen.
Oooo, that would get me so excited!! (Hey, you get your mind out of the gutter, dirty dirty!)
ETA: Yes, I could put this in the ideas forum. However, I wanted to gauge what others thought before I made a post over there. If others think this is a bad idea, or a waste of time, no reason in mentioning it in that forum and wasting some devs time....
