Empire.Kred is an online game for building real world Influence.
Players buy and sell each other, and earn currency by completing real world Social Missions.
Players choose their own username (called a ticker) and activate their own portfolio in a virtual economy. The price of a player's shares depends on their stock market and social networking activity. Players can invest in and have their shares bought by other players, which will garner them a higher share price. Players are awarded Achievements for their actions, such as advertising and connecting social identities such as Twitter. Players gain dividends from the other shares in players they invest in, which are counted as virtual currency (called Eaves).... More Info »
