1.6.4
Creative, no way in hell I could do half of that on survival, it'd take me months.
Hah. Yeah, though, I think making something like this in survival, or in my opinion, generally anything in survival would suffice more for self-righteousness and self-achievement. I think I would feel pretty awesome if I did something big like this in survival. If not more because why not.
Also aren't there shaders for a more recent version? I guess the next update should come at the next 1.8 update since 1.7.x has been mostly bugfixes and useless crap but God darn it.
