If you like playing MineCraft, then you should try BitQuest server which actually rewards the players with BitCoin.
The currency on this server are the Bits. A bit is a fraction of a Bitcoin (1/1000000) that you can obtain by killing monsters, trading with users or transfering from an outside wallet. All of it is stored on a standard Bitcoin wallet on the Blockchain.
