Does Survival at Minecraft seem too easy for you? Then try The Wasteland mod, which will turn the world into a lifeless desert. Hold out as long as possible in a post-nuclear and fairly hardcore environment.
The Wasteland completely changes the principles of generating the game world, and now it will be very difficult to find familiar resources. The main source of items for crafting will be abandoned dilapidated houses. You will also find graves in which sometimes quite valuable loot is hidden.
