There are no special features at this moment, the goal is aiming to be as close as possible to the real server, for now. In a later stage, making modifications to game logic by modifying `GameData` packets can be looked at.

Since 1.2.2 it is also possible to use hostnames instead of IPv4 addresses, these must resolve to a valid IPv4 address. |
