Other interesting examples of Explicit Gamification include the famous serious game FoldIt that facilitated AIDS research21, as well as AutoDesk’s Undiscovered Territory22, a game created for selling their very expensive 3D imaging software. There are also explicit gamification examples such as Repair the Rockaways23, which is a game similar to Farmville, but the number of bricks that are available is determined by how much is donated to support Hurricane Sandy repairs.
