Ok well Topic says alot but.
I think it would be nice to have Park or somthing with Houses that are for sell, When you buy the house by the side road or what not will have a Sign with the owners name on it..The Owner could sell it at anytime And for how ever much he wanted to.
Also if the houses had locks on the doors so you could invite your Freind over for a party and keep out the Geeks.
I think it would be cool.
Sadly it probably won't ever happen.
