Why are guys your age playing minecraft? I understand why younger kids love it, but if you are into the sandbox genre, I believe at ++ 16 years old, games like minecraft could be easily traded for something way more mature to spend all that creativity. EX: 3D modeling with 3DS Max or Blender (free).
Feel free to object, just my 0.2 cents. Every person I met who play minecraft had very immature behaviors.
