Markus Persson: We've added melons, and made both melons and pumpkins farmable so you can grow them. Both have a central stem that slowly grows to max size. When it's max size, it will randomly spawn a fruit next to it if there isn't one next to it at the moment. We might add even more farming options if needed.
The random dungeons are part of the terrain, and will contain a reason to explore them. It's likely our first boss monster may appear in the dungeons, but we haven't gotten that far in their development yet.
IGN: Can you provide more detail on the NPC villages? How large will they be? What will the NPCs be doing there? Will they live in houses? What sorts of services will they provide, if any? Can you kill them and break their stuff? Are there a limited number of villages in someone's world?
Markus Persson: I'd rather keep this secret for now, but I will say that you can choose to either help the villages or to destroy them if you wish.
