Here is a better idea: Make a new house in spawn where you might find an unkillable NPC (By you or mobs) which if right click it, it shows you questions which you can ask it. (Also, funny thing, but I caught on to the thirst thing right away and knew that there must be some kind of way to make a drinking container of some sorts. So, maybe only about 50% of players would need help.)
A blocky survival game.
