Minecraft

My current videogame addiction. Also, the current big indie success story, as its creator has become quiet rich, quite fast due to its popularity. It's an open-world sandbox, and in a much more literal way than that term is usually applied. It's also like playing with a planet-sized lego set. I could go on at some length, but others already have, so I'll just include some links here:
