Adventure

Notch said, Minecraft Version 1.7 will be the Adventure Update.

Formerly Dungeons and Levers Mode, Adventure Mode is an upcoming game mode. It will be similar to Survival, but players will not have the ability to destroy or place blocks, they will only be able to use items. The mode will become more of an adventure game, rather than a sandbox game. It is expected to be something along the lines of Notch's previous work where he had made a game similar to dungeons and dragons when he live streamed some of his programming. (Link Unavailable) Also a mod was made for Minecraft and it is a Adventure style mod. It is like what Notch is adding.
