They should add a few more things though, like cars which would be redstone, 3 iron blocks one lever, two blocks of rubber (which rubber could be received by trading with villagers) and two glass blocks, and maybe a motor cycle which would be two rubber blocks, 3 iron, redstone and a lever. And maybe the possibility to put lightning into a bottle (with the downside of getting hurt in the process to make it more fun) and maybe add snakes which would give venom and bees. And maybe hawks, which can be tamed with spider eye, but if not they would pick you up in their talons until a certain hight then drop you or something like that, doesnt have to be a bird, and then rats which would take food out of chests ( up to a certain amount of course) and maybe add some natural disasters too, and add volcanos to some biomes also. They dont have to erupt though, but they could which would make things more epic. Just a few ideas!
