Sometimes the simple things are the most interesting. An ongoing social experiment called the Curiosity Cube is a social gaming project where players are faced with a giant cube which is made up of billions of smaller cubelets. Breaking cubelets accrues points and bonuses which can be spent on tools to make ‘digging’ through to the centre of the main cube more efficient.
The purpose of the game, simply, is to get to the centre and find out what’s inside. Interestingly, the developer has recently added the ability to actually add more cubelets (by paying money) to prevent the centre of the cube being accessed (http://www.gamasutra.com/view/news/190865/Peter_Molyneux_may_have_just_monetized_trolling.php) … this has been described as monetized trolling and may be a genius move that pits players against each other in a virtual war over accessing the cube. It’s a war which the developer will win, raking in money from a free game!
I’ve started playing on my iPhone and it’s fun. More importantly it will be interesting to observe what direction the game takes in the future.
