In case you are referring to me in the last phrase of the first paragraph: I do know quite a bit about the 4 major mods ( maybe not so much for Redpower but I don't really use complex restone circuits)
It is nice you understand that some people like to use EE. I don't want to make it so that everyone uses it either.
I like building stuff. But getting everything from thin air is boring.
And I don't agree. When I play survival mode, I feel MUCH more attached to the world. I dump creative worlds like a monkey with bowel problems, but I only have one active survival mode world and/or server. And when I feel I finished or died and rage-quit, I still wait to start a new one.
Give a man a catle and he will be entertainned for 20~30 minutes.
Give him a magic backpack and the ability to punch down trees and he will be entertainned for 3~4 days or when he falls into lava, whatever comes sooner.
