According to Super Minecraft Kid , Terraria is a rip-off of Minecraft. This game is also a rip-off of Mario because it's in 2Dimensional. The creators of Terraria made this game just before Notch started development of Minecraft, working along side borrowing each other's ideas. The story is as follows:
The year is 30XX, Porky Minch was resurrected by three unknown peoples because nobody cares about them. Porky was planning to take over the world once more. You, the player, must collect gear, battle monsters, and defeat Porky Minch once and for all. How do you accomplish this? By walking right to the flag obviously!
This game has a strong following of more expert players rather than casual gamers.
