Nas Warriors

http://naswarriors.soulchain.org

Nas Warriors is a typical "hot potatoes" game where users keep buying items off each other. It is similar to Ethercraft.io. Although the items that are traded do not have value at the moment, when Nebulas allows inter-contract function calls, other developers can build off the assets of Nas Warriors (i.e. use the same assets and just add game features on top of them).
