+1 on sharable maps and making notes, putting misc markers/token on your map. Say you are exploring and you almost get your ass kicked by a powerfull monster and you had to retreat untill you can get your buds to join or get better equipment, then you should be able to mark your map and add a note that says. "Nasty monster. Be prepared and go back for revenge!"
I do not want another game that I have to spend hours after hours gathering and harvesting resources to build houses, craft items etc. I would like it if I could pay someone to do that for me, let it be other PCs or NPCs.
It would also be cool to be able to hire NPC shopkeepers if you build a shop, marketstand or a small lumbermill, so that other players can pay for your services without you having to be there or it to look like an abandoned shop
