There are many different ways to play the game Minecraft, you could run fly around creating the most excellent creations and redstone contraptions.
You could enjoy fighting for your life, building giant walls to protect you and awe inspiring mob killers. Or you might enjoy arenas where you move around, killing whatever comes out of the next cage.
Or you could hope over into Adventure and take on a mighty quest to kill Herobrine, or free villagers from the clutches of the evil witch.
I personally like to play survival, but I never have enough fan to make it longer than 3 hours in singleplayer. However, in multiplayer, it’s just beautiful. With irl friends, I could even play for several days. I also enjoy creative and testing stuff in it. Resource packs are fun to make aswell.
