Of course it isn't that bad! If you hear the concept of Minecraft, you'd say: "Oh... meh", but it's different when you actually play it. Especially if you're playing survival mode and go build something that way, or if you got a nice team to play multiplayer with It's something you got to try, and you'll be hooked immediately.

Oh, and you start the game by punching a tree til it breaks. How awesome is that?
