While it seems the English lexicon is lacking a universally accepted definition (or Urban Dictionary, anyway), the phrase often promises nonlinear gameplay with vaguely defined objectives (if any), and a heavy emphasis on exploration and just sort of fooling around within the game world itself. What if there were a sandbox game, however, where the developer gave you the tools and the know-how to make the sandbox yourself? You can't do WHATEVER you want (sandboxes still need to be filled with sand, remember), but the size of the box, the grain of the wood, the Fisher-Price toys that will litter its surface... all these factors are in your hands now. Welcome to Minecraft, an ample offering from developer Markus Persson, based on the open-source project Infiniminer by Zachtronics Industries.
