At first sight, it does not look any different from MTG or MineClone with an exception of relatively unevenly situated trees and little forest formations. On second thought, you realise that it is indeed different from anything you've seen before. Blocking your ears with earbuds to not hear the muffled screams of your minetest modding slaves, you proceed further into the game. Your failures do not face any aid, and you start thinking that Warr1024 was right, it is indeed brutal... and indifferent to your mistakes. Some may give up, some might search for help online, but only the few ones persist - the future scientists. What I really enjoy about nodecore is the fervor it has been kindly filled with and the freedom of discovery. As others stated, each element serves a single function, with no node appearing useless. And it is in fact like a test, a challenge that determines if you are a scientist by nature. The mine-test.
