No I do not. I'm sure my brother would be thrilled xD
Well, there are two methods in single player. Survival and Creative. In survival, you have a food meter and a health meter, and you basically have to try to survive without dying. If you die you lose everything in your inventory and maybe even the house you were building.
In Creative, you have access to all of the blocks with no health or food gauge, and you have complete control such as the weather, mobs (bad guys), the time of day, and you can even fly.
In multiplayer, there are all these servers with different objectives to each. Some are hunger games servers where you play the hunger games, and there can be maze servers where you find your way through mazes to get points.
