Terraria! a new game that has taken all those cool 2D games we all know, love, and thank for saving our minds from boredom, and then threw in Minecraft on top of them all!
Start the game by surviving in a randomly generated 2D world, build your kingdom with your friends, hire NPC vendors, guards, and villagers, then defend it all from the evil that is the corruption, battle bosses and their minions using magic, guns, swords and armor, and whatever else you can buy, build, or find. then once your done destroying evil, let greed take hold and go PVP, killing your former friend and pillage his kingdom. But if you aren't the one for that kind of thing then don't worry, the world is nearly endless just like Minecraft, let curiosity rule you and start exploring! dive into the never ending ancient dungeons and find treasure to show off to your friends, and then explore new places to defend from the ever present corruption. be the heroic king, or the evil tyrant, the choice is yours.
