Minecraft is a first-person building/digging game that is based on another game called Infiniminer, except that it’s prettier to look at and is playable in a browser using Java. In the game you can move around and add/remove various blocks, and that’s about it… fortunately, that’s all you really need to be able to do to have a fantastic time with it.
The creator, Notch, recently implemented a multiplayer mode, which makes the game even more enjoyable. I entered a public server where one guy was building a giant tower and two other players were helping each other with a stairway into the sky, where there were floating platforms all over the place. Someone else was asking for help repairing a road. I spent some time wandering around and eventually decided to build a Moai-like statue with a secret passage behind it that took you to an underground lake. It was pretty neat.
Minecraft is free-to-play right now, but will not be for much longer (10 euros or roughly $14 USD for pre-order). Development is moving quickly – I’ve heard of plans to implement everything from monsters and Dwarf Fortress-type features to various competitive multiplayer game modes like Capture-the-Flag. But for the moment it’s just a single-player and (mostly) cooperative sandbox. Also there’s no sound or music. But you know what, I rather like how tranquil it all feels right now…
