There are other ways to fix it, too. For example, if some players issue transactions in one block, and some confirm in the next block but not all of them, the gamestate could choose not to update until all of the transactions are confirmed, giving each player an equal chance.
This is unfortunately not very straight-forward to do. There's no network consensus about unconfirmed transactions (that's precisely why they are still unconfirmed), so one cannot take them into account for consensus-stuff like game-state transitions. (There might be more complex hacks around this in some way, but I doubt one can find a good solution that fully retains Huntercoin's trustlessness and decentralisation.)
