I know this is already a topic that a lot of people have been requested already, but my idea will be quite different. Imagine some thing like you are a minecraft character that the abiliy to move around, gather resources, move parts from place to place, ect. A lot of people will thing that this will conflict with minecraft, but no since we don't have health bar of any combat thing like that. It will be like the mode in Turboprop flight simulator, a mode that allow you to get out the vehicle and move around. This will also allow the developement of multiplayer to be possible!
That's my idea, what do you thing?
Hmm
