Its an interesting low grade graphics yet still very popular video game. Nearly everything in the world is made of square blocks. In creative mode you just build. Most of the blocks defy gravity so you can build in the sky if you like. I actually have Minecraft PE for iphone and am in the process of building a palace/temple. So far ive got the throne room done. The game also has a survival mode where you start with limited supplies and have to survive against evil mods that try to attack and kill you. You chop wood, mine stone, make tools, build shelter, etc. I understand the PC version is even more involved.
