So what is Minecraft?
It's a sandbox game centered around creative, emergent gameplay with multiple single player and multiplayer modes.
The goal is to mine, create, and if playing survival mode, to stay alive through the night.
It currently costs $13 USD or 10 euros and is alpha stage of development, though purchase buys you the final product as well, once released.
It's multiplayer survival mode is currently unfinished, but allows for creative play with unkillable monsters.
Worth noting is just how large the maps can get, with its incremental 3d voxel-square grid, that generates random maps full of cliffs, hills, mountains, caves, fields, oceans, lakes, streams, lava streams, caverns, etc. As you explore, even online, the map generates chunk grids into infinity until floating point memory restricts the mapsize. Theoretically its possible to travel 32 million blocks from the center, which at 64 million block meters (assuming each block is a meter), is approximately 8 times the surface area of Earth itself. HUGE.
Honestly the game is somewhat difficult to describe, but lots of people find it extremely addictive.
I didn't enjoy it at first, but now i'm hooked and can easily spend most of my day hacking away building things.
It's even better playing with other people, though the game is buggy, laggy, and largely unfinished it still has a way of captivating people and keeping them glued to their screens for endless hours.
Basically, if you couldn't get enough of your lego kits as a kid, you'll probably get addicted to Minecraft.
