Does it need to stand up to Terraria though? They're apples and oranges, really. Minecraft may not have boss monsters to battle in its dungeons, but it outpaces Terraria every step of the way when it comes to simply exploring. The very 2D nature of Terraria makes it boring in terms of creating worlds, which is exactly what Minecraft excels at. Not that I'm saying Minecraft is perfect, but it is still in beta. :P
