Differences from Minecraft

Minetest

The main difference are the goals. While Minecraft is a proprietary completed sandbox/survival game, Minetest is a free software work-in-progress game engine which supports various voxel games in the likes of Minecraft, InfiniMiner, etc. See Games for more about this. It also allows modding at its core.

Other differences of Minetest compared to Minecraft:

• Designed for low-end hardware
• Native modding support with the Lua programming language
• Mods work server-side, you can join any random server and it will work out of the box, no matter what amount of crazy mods the server is using
• Supports protection systems (to protect your buildings from griefers)
• World size is ca. 60000 blocks in all 3 dimensions
• More map generators
• Crafting recipes are not automaticlly mirrored
• Smelting time of items may differ on a per-item basis
• No dual wielding
• A rather small base set of server commands
• A sophisticated system of privileges
• Simpler liquid physics
• Built-in minimap and radar (press F7 to view)

Also see Minetest.

Gotchas

• No game modes (damage and creative mode are treated seperately)
• Liquids in general do not protect you from fall damage if still hit the floor

Minetest Game

Note: Keep in mind that Minetest Game does not want to be an exact clone of Minecraft, but it is still heavily influenced by it. If you feel many features are missing Minetest Game, you might either try out a different games or add mods. Remember that Minetest Game is only one of many games for Minetest.
