Lego Loco is a Lego-branded children's computer game for the Microsoft Windows platform. It is a simple open-ended construction game with a slight emphasis on Rail Transport. The aim of the game is to construct a town in which Lego people can live. The game lacks any real challenge (there being no construction costs, no running costs, and no budget in general). That, coupled with its very colourful graphics, help to designate its target audience as children aged between 6 and 12, although it is often enjoyed by other age groups.There are several easter eggs in the game, including the ability to breed animals in a field, the transformation of skyscrapers into giant robots, the appearance of the Loch Ness Monster and even season-themed objects.
