As an online survival sandbox, Morterra has a beautiful aspect of creativity. Here is an example of creativity through players constructing their base to perfection. Everything in Morterra can be destroyed - nothing is permanent, and all construction objects can be placed by players to their liking. It is a key part of the game to build a secure base to sleep in while you're offline, so it's important for users to do so freely. Plants can be planted, and then be harvested to reduce hunger.

I would pay for it if it wasn't a mmo but more like single or multiplayer (LAN)
