I don't like adding this message just to get round the fact that we don't have
an IPC_MESSAGE_ROUTED6. Would we be better collecting together the data in the
initialize message into a number of structs or classes (e.g. one for player data
and one for the item to be played) and hence incorporating this data in the
initialize message? Alternatively we could create IPC_MESSAGE_ROUTED6.
