I was starting a new game and after making my sim I wanted a large lot to start on but looking around I only saw one he could move into. It was a 64x63. Wonder why the odd lot size.
So I thought I would use edit town to add 64x64 somewhere but when I entered edit town I saw two empty lots that where 64x64 but they was set to a commercial lot instead of residential.
There are also some different size lots around town that are empty but set to commercial lots. So if you don't see what yo want check in edit town for empty lots.
