I have a feeling that this has been requested to hell and back and shot down by Jorb but I did a quick search and only found passing requests in other threads.
Im not talking about a private server or a LAN server. I'm talking about a version where there are no NPCs no nothing just you alone. Think Don't Starve in the Legacy world. I would pay for this. Anyone else? The biggest concerns would be wild animals and finding that perfect spot to set up. I would be okay with this. Some may say there is no challenge but frankly I don't care.
