Is Minecraft the new Doom? It feels that way, as it's increasingly playable on every platform under the sun -- including the finally available Raspberry Pi port. After a false start in December, Mojang has posted Minecraft: Pi Edition for consumption on the tiny ARM PC. The public release is a cut-down version of Pocket Edition that fits into the system's limited resources, including networking if you've bought the $35 Raspberry Pi unit. The limitations reduce the chances that you'll be creating virtual electronics with a device that was originally meant for very real electronics, but try not to let the irony sting: it's a chance to create blocky virtual worlds on a computer that costs less than a good night on the town.
