... i just finished condensing my resident, shopping, and orchard areas yesterday.
Right now I have my own make shift attractions in my shopping area (along with nooks, ables, and museum) so I have room to move out those items/displays for new buildings.
I haven't thought about that at all actually, but I'm sure I can find space somewhere, if not I can shuffle things around, it is changeable at any time luckily
Map expansion by double or triple
Cap increase to 20 villagers.
Building for each personality type aka jock get gym, lazy get game room/arcade center, Snooty get book shop, and etc...
Sub-personalities (credit to whoevers said this) for all personality types
And much more. Nintendo hold the power to make this the greatest AC game ever (well we need mean personality back).
