It's not about wanting to cram all my resources into my backyard so I can keep them to myself. It's more like trying to give my backyard/front yard a theme. I want my backyard to be bog-themed, with barnacles and jellisacs and eggplants (and one spice and one gas) and peat bogs and a herb garden. But there's not enough space to fit all of that, except maybe one of each, and I want multiple because I'm a hoarder.
So, bigger backyards, please? I've imagined mine to the max.
