As far as I can tell, Dinkum is pretty much Australian Stardew Valley, but without any kind of story. It takes quite a while to get going but the more you play, the more there is to do. You start in the outback with nothing, and slowly entice specialists to join your little town, like the vendor, fisherman and museum guy. As they visit and you do jobs for them, eventually you can build them a shop/house and they'll move in. There's the same kind of crafting / refining stuff, mining and tool upgrading, but with a 3D world where you can build in any way you like. It's a little rough around the edges, but worth trying.
